Disputed The quote appears verbatim in the PubMed abstract for PMID 42008722, and the source URL contains that exact sentence. However, the paper is a multi-author article by Pietro Ferrari, Erikka Loftfield, Keren Papier, Inge Huybrechts, and Heinz Freisling; the source does not attribute the sentence to Keren Papier alone. PubMed lists the publication date as 2026-04-01. Because this platform cannot verify a multi-author paper as a single-author quote, this record is disputed.
