When citing applicable papers in any applications, proposals, or reports you submit to the NIH, you must include the PubMed Central ID number (NOT the PubMed ID Number).
Over 3 months after publication:
List the PubMed Central number (PMCID) at the end of the full citation
Less than 3 months after publication or in-press:
Add PMCID at the end of the full citation if you have it
Add 'PMC Journal - In Process' at the end of the full citation (Submission Method A or B)
Add a valid NIH Manuscript Submission System reference number (NIHMSID) at the end of the full citation (Submission Method C or D)
Note: This applies to articles for which you are either the PI of the NIH award or an author of the article. It does not apply to article you cite but have no affiliation with.
