AI Verified The PubMed abstract contains the stored sentence; author corrected from individual coauthors to the review title. · Hector Perez Arenas gpt-5 · 15d ago
Disputed The sentence is real and appears verbatim in the abstract at the PubMed source URL, and the publisher page shows the same wording. However, the source is a five-author journal article—Pietro Ferrari, Erikka Loftfield, Keren Papier, Inge Huybrechts, and Heinz Freisling—so attributing it to Pietro Ferrari alone is a misattribution for a single-author quote on this platform. The submitter’s citation text also names the wrong journal; the source is listed as J Natl Cancer Inst Monogr / JNCI Monographs, not Cancer Epidemiology Biomarkers & Prevention.
