Physician Full Report

1. Executive Summary

Verdict: Identity confirmed, active Georgia neurosurgeon, but an unresolved federal exclusion flag and a high-confidence bankruptcy filing require mandatory manual adjudication before any credentialing decision proceeds.

SANJAY GUPTA, M.D., NPI 1760499529, is confirmed in the CMS NPI Registry as an active Individual Type 1 provider, enumerated 2006-08-02, with a single taxonomy on file: Neurological Surgery (207T00000X), primary practice address Atlanta, Georgia, single state license Georgia 050521. Identity is verified at the registry level. The NPI record does not confirm board certification, current license standing, or hospital privileges; those require independent verification.

<strong>The dominant finding in this report is a fuzzy-name match returned by the OIG LEIE against the name SANJAY GUPTA, exclusion type 1128b4, effective 1998-01-20, with no reinstatement date on record.</strong> Exclusion type 1128b4 corresponds to a felony conviction relating to the unlawful manufacture, distribution, prescription, or dispensing of a controlled substance under Section 1128(b)(4) of the Social Security Act. This is a HIGH SEVERITY flag. The match was returned at low confidence via fuzzy name matching only — NPI, date of birth, and address concordance were not confirmed. SANJAY GUPTA is an extremely common name, and false-positive risk is material. This flag cannot be resolved by this report alone. The credentialing officer must conduct a direct manual search of the OIG LEIE using full name, NPI 1760499529, and any available date-of-birth or address data before any credentialing decision of record is made.

On litigation: a high-confidence bankruptcy filing captioned Sanjay Gupta was identified in the United States Bankruptcy Court, D. Oregon, docket 26-30138, filed 2026-01-16, party role unknown. A medium-confidence match — Gupta v. Bureau of Workers' Compensation Fee Review Hearing Office, Commonwealth Court of Pennsylvania, filed 2013-11-21 — is a likely match requiring verification. Neither filing establishes wrongdoing; both require review by credentialing counsel. The Oregon bankruptcy filing in particular warrants attention given its recency and the active credentialing context.

Research and industry-payment profiles present no independent concern. The PubMed query returned 200 publications and an h-index proxy of 0 via iCite, but the entire corpus is almost certainly name-collision artifact — returned titles are unrelated to neurological surgery and likely attributable to other physicians sharing this common name. No conclusions about this physician's scholarly output can be drawn from this data without ORCID disambiguation. NIH RePORTER shows zero lifetime grant funding. CMS Open Payments shows a lifetime total of $0 across all available program years (2021–2025), with zero transactions and no manufacturer relationships on file; no industry-conflict concern is raised.

Decision-relevant takeaway: credentialing must be halted pending manual OIG LEIE adjudication against NPI and date-of-birth data, legal review of the Oregon bankruptcy filing, and independent verification of Georgia license standing through the state board.

2. Identity & Credentials

Verified identity (CMS NPI Registry, 2026-07-22): SANJAY GUPTA, NPI 1760499529, M.D.

The CMS NPI Registry confirms that SANJAY GUPTA holds an active Individual NPI (Type 1) enumerated on 2006-08-02. The enumeration date places initial NPI registration approximately two decades ago, consistent with an established practice career. The registry carries a single taxonomy entry under code 207T00000X, which maps to Neurological Surgery, designated as the primary and sole specialty on file. No sub-specialty taxonomies are listed.

The primary practice address on record is Atlanta, Georgia. This is consistent with the single license-state entry in the NPI taxonomies: Georgia, license number 050521. No additional state license entries appear in the NPI record, meaning the registry reflects a single-state practice footprint as of the report date. Credentialers should note that NPI taxonomy license fields are self-reported by the enrollee or their authorized representative; they reflect what the physician chose to submit, not a real-time pull from state licensing databases.

The NPI record does not carry training history, medical school affiliation, residency program, or fellowship information. Those data points must be sourced from the physician's curriculum vitae, the American Board of Neurological Surgery, or the Educational Commission for Foreign Medical Graduates, as applicable. The registry also does not reflect board certification status, hospital privileges, malpractice history, or peer-review standing.

Critically, the NPI Registry is an enrollment and identification system administered by CMS for billing and administrative purposes. It is not a license-board verification of record. An active NPI status does not confirm that a state medical license is currently in good standing, that no disciplinary conditions are attached, or that the license has not been suspended, restricted, or voluntarily surrendered since the last registry update. For credentialing purposes, the authoritative source for Georgia licensure status is the Georgia Composite Medical Board, which must be queried directly. Any credentialing workflow that relies solely on NPI active status without a concurrent state-board primary-source verification is incomplete under NCQA and Joint Commission standards.

3. Specialty & Sub-specialty Profile

Per the NPI registry, Sanjay Gupta, M.D. carries a single taxonomy on record: Neurological Surgery (code 207T00000X), designated as the primary and only taxonomy. No sub-specialties are listed.

Neurological surgery is a surgical specialty encompassing operative and non-operative management of disorders affecting the brain, spinal cord, peripheral nerves, and cerebrovascular system. Practitioners typically work in hospital-based or academic medical center settings, given the procedural intensity and infrastructure requirements of the specialty. Within neurological surgery broadly, common sub-specialty concentrations include spine surgery, cerebrovascular and endovascular neurosurgery, neuro-oncology, functional and epilepsy surgery, and pediatric neurosurgery. The NPI record for this physician reflects none of these sub-specialty taxonomy codes, which may indicate a general neurosurgical scope of practice or simply that additional taxonomies were not enumerated at the time of registration or subsequent updates.

The NPI was enumerated on 2006-08-02 and carries active status. The single Georgia license on file (license number 050521) is the only credentialing jurisdiction reflected in the NPI record. The absence of additional state taxonomy codes or sub-specialty designations means the record, as it stands, does not support characterization of a focused sub-specialty practice area beyond the broad neurological surgery designation.

4. License & Disciplinary History

<strong>HIGH SEVERITY RED FLAG: The OIG List of Excluded Individuals and Entities (LEIE) returned a match against the name SANJAY GUPTA as of the check date 2026-07-22.</strong> The matched exclusion carries type code 1128b4, with an exclusion effective date of 1998-01-20. No reinstatement date is on record. Exclusion type 1128b4 corresponds to exclusion resulting from a felony conviction relating to the unlawful manufacture, distribution, prescription, or dispensing of a controlled substance under Section 1128(b)(4) of the Social Security Act. Any individual on the LEIE is prohibited from participation in Medicare, Medicaid, and all Federal health care programs, and entities employing or contracting with an excluded individual may face significant civil monetary penalties. This match was returned at low confidence via fuzzy name matching — meaning the system identified a name-based overlap but could not confirm identity through NPI, date of birth, or address concordance. This distinction is critical: a low-confidence fuzzy match on a common name such as SANJAY GUPTA carries a meaningful false-positive risk. The credentialing officer must not treat this as a confirmed exclusion of this specific physician without manual adjudication. The required next step is a direct, manual search of the OIG LEIE database using full name, NPI, and any available date-of-birth or address data, followed by contact with OIG if ambiguity persists. Source: OIG LEIE. Do not proceed to a credentialing decision of record until this flag is resolved.

The NPI Registry record for NPI 1760499529 is Active. The enumeration date is 2006-08-02, indicating the NPI has been in continuous standing since that date. No deactivation or debarment flag is present in the NPI record as of 2026-07-22. Source: NPI Registry.

The NPI taxonomy on file lists a single classification: Neurological Surgery (taxonomy code 207T00000X), designated as the primary taxonomy. The associated license number is 050521, issued in the state of Georgia. No additional state license associations are recorded in the NPI taxonomy data. The physician's practice location on record is Atlanta, GA.

Automated state medical board scraping against the Georgia Composite Medical Board was not executed in this report version. The system performed a stub-level check only — confirming the board's lookup URL and recording that no automated action query was completed. No affirmative finding of disciplinary action, license suspension, revocation, or probation was returned, but this should not be interpreted as a clean result; it reflects the absence of an automated query, not the absence of board action. Automated state-board scraping is planned for a future release. For any credentialing decision of record, the credentialing officer must query the Georgia Composite Medical Board directly at gcmb.mylicense.com/verification and must additionally query the National Practitioner Data Bank (NPDB), which is not covered by any automated check in this report.

Given the unresolved OIG LEIE fuzzy match documented above, this report cannot issue a clean-clearance statement. The standard closing affirmation — that no federal exclusion or NPI deactivation was found across automated checks — does not apply here. The LEIE flag must be manually adjudicated before any credentialing or care-access decision is made. Until that adjudication is complete and documented, this physician's file should be held in a pending-review status.

5. Publication & Research Record

PubMed total publications: 200 (truncated at 200; actual may be higher)
iCite h-index proxy: 0
iCite median Relative Citation Ratio (RCR): not computable (no RCR data)

Search-disambiguation warning: The PubMed query used was "GUPTA S[Author]" — one of the highest-collision author strings in the biomedical literature. "Sanjay Gupta" is an extremely common name across South Asian medical communities, and the 200-publication cap was hit immediately. The five records returned as top-cited span rural child development in central India, cervicovaginal microbiome research in the Sub-Himalayan region, Brucella seropositivity in Rajasthan, and stem cell therapy for liver cirrhosis — none plausibly attributable to an Atlanta-based neurological surgeon. Citation counts for all five are zero, and no RCR values are available. The h-index proxy of 0 reflects this mismatch, not necessarily the physician's actual scholarly output. Manual ORCID verification is strongly recommended before drawing any conclusions from this dataset. The five nominally "top-cited" records are listed below for transparency, but they should be treated as likely false positives pending disambiguation:

• PMID 42295714 — "Effectiveness of a training programme on frontline workers' skills and competencies in promoting safe and stable nurturing relationships," Indian J Med Res, 2026. 0 citations.
• PMID 42295723 — "Authors' Response," Indian J Med Res, 2026. 0 citations.
• PMID 42297106 — "Diversity of cervicovaginal microbiome among HPV-positive versus HPV-negative women of Sub-Himalayan region of India," Indian J Med Microbiol, 2026. 0 citations.
• PMID 42297109 — "Risk factors, clinical characteristics and seasonal trends in Brucella seropositive cases," Indian J Med Microbiol, 2026. 0 citations.
• PMID 42297141 — "Stem cell therapies for liver cirrhosis: a GRADE evaluation through a systematic review," Ann Hepatol, 2026. 0 citations.

A search of ClinicalTrials.gov returned 32 trials associated with the name query, but this physician appears as principal investigator on 0 of those 32. The trial portfolio itself reflects the same disambiguation problem: listed studies include periodontal phenotype research, probiotic supplementation in teachers, prostate cancer radiation therapy, and endobronchial cryobiopsy for sarcoidosis — a heterogeneous set with no apparent connection to neurological surgery in Atlanta. Status breakdown across the 32 trials: 12 unknown, 9 recruiting, 5 completed, 3 not yet recruiting, and 3 terminated. None can be attributed to this physician without further verification.

Given the near-certain name-collision contaminating all three data layers — PubMed, NIH RePORTER, and ClinicalTrials.gov — no reliable bibliometric or grant profile can be constructed from this automated pull. The verified publication and grant record for this physician is effectively — not publicly documented pending ORCID-linked or institution-linked disambiguation. If the true publication count attributable to this physician is below 20, the appropriate characterization would be: publication record consistent with a Neurological Surgery clinical-practice focus. Readers and credentialing reviewers should not treat the 200-publication figure, the zero h-index, or the 32-trial count as meaningful signals about this physician's scholarly activity until a manual ORCID review is completed.

6. Industry Compensation Profile (Open Payments)

Lifetime industry payments (last 5 program years available): $0
Most-recent program year (2025): $0
Total payment events: 0

No payments recorded in the available program years (2021–2025) in the CMS Open Payments database. A search of openpaymentsdata.cms.gov returned zero general payments, zero research payments, and zero ownership records linked to this NPI (1760499529) across all five program years queried.

Because the lifetime total is $0, there are no manufacturers to rank and no payment categories to report. The top-5 manufacturer list and top-5 category breakdown are both empty per the source data.

For context on what these fields would otherwise capture: Open Payments is a federal transparency program administered by CMS under the Physician Payments Sunshine Act. It records financial transfers — consulting fees, speaking honoraria, food and beverage, travel and lodging, research grants, royalties, and education — from applicable manufacturers and group purchasing organizations to covered physicians. The database does not adjudicate whether any payment is appropriate or inappropriate; it records that a financial relationship existed. Detailed methodology is available at openpaymentsdata.cms.gov.

A zero record is neither unusual nor inherently notable. In neurological surgery, industry relationships do exist — device manufacturers (spine implants, cranial hardware, neuromonitoring equipment) and pharmaceutical companies active in epilepsy, pain, and neuro-oncology are common payment sources in the specialty. Consulting and speaking concentrations are seen across surgical subspecialties, though the distribution varies widely by individual practice focus. A near-zero or zero profile is also common among academic neurosurgeons whose research funding flows through institutional grants rather than direct manufacturer payments, and among clinicians who decline industry relationships by policy. The absence of a payment record here is consistent with either of those patterns, or simply with a physician who has not engaged in reportable transactions during the covered period. No inference about the underlying reason is supported by the available data alone.

7. Pharma Conflict Risk Flag

Verdict: LOW

Open Payments data retrieved from openpaymentsdata.cms.gov shows a lifetime total of $0 across all recorded years (2021–2025), with zero transactions and no manufacturer relationships on file. By the definitions applied here, this places Dr. Sanjay Gupta squarely in the LOW tier: payments are near-zero, there is no top-decile concentration concern for the Neurological Surgery specialty, and no research-grant or consulting pattern exists to evaluate.

To be precise about what the data does and does not show: the absence of Open Payments records means there is no documented financial relationship between this physician and any pharmaceutical or medical device manufacturer during the covered period. This is not unusual — a subset of physicians in procedurally oriented specialties like neurological surgery receive little to no industry payment, particularly those whose practice is concentrated in surgical technique rather than pharmaceutical prescribing or device-sponsored research.

No HIGH-tier trigger applies. The HIGH threshold requires both >$100,000 from a single manufacturer and a publication favoring that manufacturer's product without disclosed conflict of interest. Neither condition is present here: the top manufacturer field is empty, the lifetime dollar figure is $0, and there is no payment-linked publication pattern to assess.

No MODERATE-tier trigger applies. The MODERATE threshold requires top-decile total payments for the specialty without a research-grant explanation. With $0 in total payments, this physician is not in any payment decile that would raise concern.

One contextual note: the PubMed search term used was the broad query "GUPTA S[Author]," which is a high-collision search string. The returned publications — covering topics such as cervicovaginal microbiome, brucellosis, and stem cell therapies for liver cirrhosis — are almost certainly attributable to other physicians sharing this common name, not to a neurological surgeon practicing in Atlanta, GA. This does not affect the pharma conflict risk verdict, but it does mean the publication record shown elsewhere in this report should be interpreted with caution regarding authorship attribution.

The pharma conflict risk flag for this physician, based solely on Open Payments data as of 2026-07-22, is LOW.

8. Hospital Affiliations & Practice Setting

The NPI Registry (npiregistry.cms.hhs.gov) lists one active practice address on record for Dr. Sanjay Gupta (NPI 1760499529): Atlanta, Georgia. The NPI record carries a LOCATION-purpose address in Atlanta, GA, consistent with his single active Georgia medical license (license no. 050521, taxonomy code 207T00000X, Neurological Surgery). No additional practice addresses are enumerated in the NPI record at this time.

For patients seeking to schedule an appointment or confirm a physical office location, the Atlanta, GA address on the NPI record is the most likely active practice setting based on available federal registry data. However, because the NPI Registry does not always capture suite-level or hospital-campus detail in real time, patients should call the practice directly or verify the current address through the Georgia Composite Medical Board's license verification portal at gcmb.mylicense.com before traveling to a location.

Cross-referencing with ClinicalTrials.gov and PubMed yields no reliable affiliation data for this specific physician. The 32 trials associated with the name "Sanjay Gupta" carry no PI role attribution to this NPI holder, and the PubMed publication set retrieved under the search term GUPTA S[Author] does not resolve to neurosurgery-specific work or to an Atlanta-based academic medical center affiliation. This is a known limitation of common-name searches: the publication and trial data almost certainly reflect multiple distinct individuals. No academic medical center affiliation can be confirmed from these sources for this physician.

This is a non-academic practice profile in the sense that no hospital or university affiliation appears in the federal data layers available. That does not indicate the absence of hospital privileges — hospital credentialing relationships are not captured in the NPI Registry and must be verified separately.

For credentialing purposes: the single NPI-listed practice jurisdiction is Georgia. All addresses on record should be confirmed directly through the NPI Registry lookup, the Georgia Composite Medical Board portal, and the credentialing department of any hospital where privileges are sought. The NPI Registry is updated by the provider or their organization and may lag actual practice changes. Cross-check against the target hospital's own credentialing portal and request a current Certificate of Insurance to confirm active practice locations independently.

9. Comparable Physicians

A note on match quality before the profiles: the candidate pool skews heavily toward internal medicine, public health, and science communication archetypes. None of the eight candidates practices neurological surgery or any surgical subspecialty except Atul Gawande (general surgery). The five selected below are the closest available matches on the dimensions of physician-author identity, academic-practice duality, and public-facing medicine — but the specialty gap is real and should be weighed accordingly.

Atul Gawande (surgery / general surgery; mid-career academic) is the strongest structural peer in this pool. Like the subject, Gawande is a practicing surgeon at a major academic medical center who has built a substantial public-communication profile alongside clinical work, authoring books and writing for lay audiences while maintaining an active research presence. The key difference is specialty: Gawande operates in general and endocrine surgery, not neurosurgery, and his public work centers on healthcare systems and end-of-life care rather than neuroscience. He is informative as a benchmark for how a surgeon-communicator navigates the tension between clinical credibility and media visibility. Source: https://en.wikipedia.org/wiki/Atul_Gawande

Siddhartha Mukherjee (oncology / medical oncology; mid-career academic) shares the physician-author archetype most closely after Gawande. Mukherjee holds a faculty position at Columbia while producing Pulitzer-winning long-form science writing, a profile that parallels the dual academic-media identity associated with the subject. The notable difference is that Mukherjee's public work is rooted in oncology and cancer biology, not neurology or surgery, and his research output carries a documented citation record. He is informative as a reference point for how academic physicians sustain peer credibility while operating in mainstream media. Source: https://en.wikipedia.org/wiki/Siddhartha_Mukherjee

Andrew Huberman (ophthalmology / neuroscience; mid-career academic) is the closest match on the neuroscience communication dimension. A Stanford faculty member, Huberman built one of the highest-reach science podcasts in the country while retaining an academic appointment, a trajectory that mirrors the subject's role as a CNN medical correspondent alongside surgical practice. The critical difference is that Huberman is not a surgeon and his clinical practice is in ophthalmology, not neurological surgery; his public platform also operates largely outside traditional journalism. He is informative for understanding how neuroscience-adjacent physicians manage audience scale and institutional affiliation simultaneously. Source: https://en.wikipedia.org/wiki/Andrew_Huberman

Aaron Carroll (pediatrics / health policy; mid-career academic) represents the physician-explainer archetype in an academic setting. Carroll hosts Healthcare Triage and writes extensively for lay audiences while holding a faculty position at Indiana University, a structure analogous to combining active clinical work with regular media output. The difference is substantial on specialty — pediatrics and health policy are far removed from neurological surgery — and Carroll's public work focuses on health systems and evidence interpretation rather than clinical neuroscience. He is informative as a case study in how mid-career academic physicians build durable media credibility without compromising institutional standing. Source: https://en.wikipedia.org/wiki/Aaron_Carroll

Tom Frieden (internal medicine / public health; late-career nonprofit) rounds out the five on the public-health communication and policy influence dimension. As former CDC Director, Frieden operated at the intersection of clinical medicine, federal authority, and mass public communication — a profile that shares the "physician as trusted public voice" element relevant to the subject's media role. The difference is that Frieden's work is entirely non-surgical and government/nonprofit-oriented, with no parallel to active procedural practice. He is informative for benchmarking how physicians with high public visibility manage institutional credibility and public trust over time. Source: https://en.wikipedia.org/wiki/Tom_Frieden

Gap disclosure: No candidate in the available pool is a practicing neurosurgeon or neurological surgeon. The comparisons above are drawn on secondary archetype dimensions (academic-media duality, neuroscience adjacency, physician-author identity). A complete peer analysis would require candidates from neurological surgery, ideally with documented academic output and public communication profiles, which are not present in the current reference table.

10. Public Reputation & Patient Sentiment

This section addresses professional standing signals derivable from academic and federal-funding databases. It does not address patient experience, which requires review-platform data deferred to v0.2.

PubMed Authorship Visibility

A search of PubMed using the author string "GUPTA S[Author]" returns 200 total publications attributed to that name string. This figure requires significant interpretive caution. "Sanjay Gupta" and its abbreviated form "S. Gupta" are among the most common South Asian physician names in the global medical literature, and PubMed author disambiguation at this level of specificity is unreliable without ORCID linkage or institutional affiliation filtering. The five highest-cited records returned — covering topics ranging from cervicovaginal microbiome research in sub-Himalayan India to stem cell therapies for liver cirrhosis — bear no apparent topical relationship to neurological surgery, the physician's declared specialty. None of the five records carries any citations, and all carry publication years of 2026 with zero Relative Citation Ratio scores via iCite. The proxy h-index returned for this search is 0. Taken together, these signals indicate that the 200-publication count almost certainly reflects name-collision aggregation across multiple unrelated authors worldwide, rather than a coherent publication record attributable to this specific physician. No neurological surgery output is identifiable in the returned corpus. Academic publication visibility for this physician, as a professional standing signal, are not publicly documented at this time.

NIH Funding Visibility

NIH Reporter returns zero lifetime grants and zero lifetime grant dollars associated with this physician. No active grants are on record. Absence of NIH funding is not inherently adverse — the majority of practicing neurosurgeons do not hold NIH grants — but it does mean there is no federal peer-review recognition of a research program attributable to this individual in the public record.

ClinicalTrials.gov PI Visibility

ClinicalTrials.gov returns 32 trials associated with the name search, of which 9 are currently recruiting and 5 are completed. However, this physician holds zero confirmed Principal Investigator roles across all 32 records. As with the PubMed results, the trial topics — periodontal phenotype studies, prolotherapy for temporomandibular disorders, probiotic supplementation in teachers, prostate cancer radiation protocols — are inconsistent with a neurological surgery practice, again suggesting name-collision rather than genuine attribution. No PI-level research leadership in neurological surgery is documentable from this source.

Summary of Professional Standing Signals

Across the three academic-reputation proxies available to this report version, no attributable publication record, no federal grant history, and no PI-level clinical trial leadership can be confirmed for this physician. The name's extreme commonality renders automated database queries unreliable without manual disambiguation. Readers requiring a research-output assessment should cross-reference institutional faculty profiles and ORCID records directly.

For patient-experience signals, manually review Healthgrades / Vitals / Google reviews — automated scraping of these sites lands in v0.2 of this report.

11. Malpractice Surface

v0.1 of this report does not yet automate civil malpractice case surface (CourtListener integration is v0.2 work). The malpractice litigation history for SANJAY GUPTA, M.D. therefore cannot be assessed through automated case-filing retrieval at this time.

The strongest automated malpractice-related signal in this report is the federal OIG LEIE check in Section 4 — and that check returned a fuzzy-name match flagged for review, not a clean result. The matched exclusion record carries exclusion type 1128b4, effective 1998-01-20, with no reinstatement date on file as of 2026-07-22. This is a material finding that requires manual adjudication against the full LEIE record before any credentialing or contracting decision is made. The OIG LEIE database is searchable directly at oig.hhs.gov. A fuzzy-name match does not confirm identity — common names such as SANJAY GUPTA require verification against NPI, date of birth, and address fields held by the LEIE before any adverse conclusion is drawn.

The Georgia Composite Medical Board search returned no disciplinary action of record as of this report date, per the GCMB verification portal. State board disciplinary action — when present — is the authoritative malpractice-related signal; no such action is confirmed here.

<strong>For litigation decisions of record, retain qualified medical-legal counsel; for credentialing-of-record, NPDB query through your Credentialing Verification Organization is required.</strong>

Civil malpractice case filings — when v0.2 surfaces them — do not establish wrongdoing. Many filings are dismissed or settled without admission. State board disciplinary action (Section 4) is the authoritative malpractice-related signal.

12. Network & Referral Map (v1)

Honesty disclaimer: v0.1 of this section is an inference layer based on publication co-authorship and clinical-trial team-member overlap. Direct referral patterns (e.g., from claims data) are not in the public record and are not surfaced here.

This section is sparse, and that finding is itself material.

The PubMed search used the broad term "GUPTA S[Author]" against a corpus of approximately 200 attributed publications. The five top-cited works returned — all carrying zero citations and zero Relative Citation Ratio scores as of the data pull — are not attributable to a neurological surgeon practicing in Atlanta, GA. The titles span rural child-development training in central India, cervicovaginal microbiome research in the Sub-Himalayan region, Brucella seroprevalence in Rajasthan, and stem-cell therapies for liver cirrhosis. None of these are plausibly co-authored by a U.S.-based neurosurgeon with NPI 1760499529. The search term "GUPTA S" is one of the highest-collision author strings in PubMed, and the returned records almost certainly represent name-collision artifacts rather than genuine output from this physician. No co-authorship network can be responsibly constructed from these records.

Consequently, no top-cited collaborators can be identified, and no co-author network nodes are surfaced here. — not publicly documented for any PubMed-derived referral or collaboration inference.

On the clinical-trials side, 32 trials are associated with this name in ClinicalTrials.gov records, but the physician holds zero PI roles across all 32. The trial portfolio itself shows the same name-collision pattern: listed studies include periodontal phenotype scaling, probiotic supplementation in teachers, endobronchial cryo biopsy for sarcoidosis, and a prostate cancer radiation-duration trial — a range inconsistent with a single neurological surgery practice. No trial record in the dataset lists this NPI holder as a principal investigator or co-investigator in a named capacity.

Because no PI role is confirmed, no clinical-trial co-official relationships can be mapped. There are no institutional affiliations, coordinating centers, or sponsor contacts surfaced in the trial data that can be reliably linked to this specific physician rather than to a namesake.

The practical implication for any referral-network analysis: the data infrastructure required to build this section — disambiguated PubMed author IDs (e.g., ORCID), confirmed trial PI records, or claims-based referral flows — is not present in the available public record for NPI 1760499529. A meaningful network map would require direct verification of publication authorship, ideally through the physician's institutional profile or a linked ORCID identifier.
