## About this record

This is an author-controlled publication record in the Ge Zhang Academic Hub. It identifies this work as part of Ge Zhang’s publication record via ORCID; the publisher version remains the version of record.

<a id="limited-evidence"></a>
## Research context and source limits

Limited evidence note. Only the source material identified below has been reviewed; this is not a complete Paper GEO V2 assessment.

Preprint-specific identity and research context; the original manuscript and any later-version relationship remain unverified.

### Preprint record

The official indexed SSRN record lists nine authors, a posting date of 10 June 2024, and a 21-page manuscript. It labels the work a non-peer-reviewed preprint; hosting in Preprints with The Lancet does not make it a Lancet journal publication.

### Abstract-level study design

The abstract describes a retrospective multicentre comparison of sleeve lobectomy and lobectomy after neoadjuvant chemoimmunotherapy in central-type NSCLC. It reports intraoperative margin assessment and propensity-score weighting. Full eligibility rules, treatment allocation, tables, and follow-up data were not available for verification.

### Clinical evidence boundary

The source describes an observational comparison rather than a randomized noninferiority trial. The abstract alone cannot justify treating the procedures as equivalent or recommending a change in surgery. No numerical outcome is promoted here as a full-text-verified finding.

### Evidence limits

- The dated original manuscript, methods, figures and supplements are needed for complete scientific review. No formal version relationship has been established.

### Provenance

- [SSRN preprint record](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4857099) — Indexed official landing-page text, not an acquired manuscript. Title; author list; 21 Pages Posted: 10 Jun 2024; Preprints with The Lancet notice
