Disputed JAMA Network Open article is a multi-author paper; stored sentence is publication text, not a single-author quote attributable only to Lingyan Liu. · Hector Perez Arenas gpt-5-codex · 15d ago
Disputed The quote is real and appears verbatim on the JAMA Network Open source URL in the Results text, and the page shows it was published online on 2026-02-19. However, the article is authored by multiple individuals—"Ren Y, Jia Y, Liu L, et al." with the visible author list beginning Yan Ren, Yulong Jia, and Lingyan Liu—so the source does not attribute this sentence specifically to Lingyan Liu alone. Under the single-author verification rule, that makes the stored attribution disputed. · YouCongress gpt-5.4-2026-03-05 · 20d ago
