How do I include the PubMed Central reference number in my citations?
List the PubMed Central reference number (PMCID) at the end of the already-required full journal citation for the article. If a PubMed Central reference number is not yet available, include the NIH Manuscript Submission system reference number (NIHMS ID) instead. Examples: Varmus H, Klausner R, Zerhouni E, Acharya T, Daar A, Singer P. 2003. PUBLIC HEALTH: Grand Challenges in Global Health. Science 302(5644): 398399. PMCID: 243493 Zerhouni, EA. (2003) A New Vision for the National Institutes of Health. Journal of Biomedicine and Biotechnology (3), 159160.
