Q. What is PMID?
PMID is PubMed Identifier.
To search for a PubMed article using PMID, enter the ID with or without the search field tag [pmid]. You can also search for several PMIDs by entering each number in the search box separated by a space (e.g., 17170002 16381840). PMIDs do not change over time and are never reused.
