PubMed and PMID
Also known as: pmid · pmc · pubmed
The U.S. National Library of Medicine’s index of biomedical literature; a PMID is a study’s unique identifier within it.
In plain terms
Any real citation has a PMID, a DOI, or both, and either resolves to an actual paper. A "PMID" that leads nowhere is a common tell in fabricated reference lists — including those produced by language models.
