Journal articles often mention the funding agency who provided the support for the research on which the article is based. Since 1981, the National Library of Medicine (NLM) has routinely included the grant or contract number(s) in the MEDLINE/PubMed citation when the funding support is from one of the US Public Health Service (PHS) agencies.
The National Institutes of Health (NIH), the Centers for Disease Prevention and Control (CDC), and the Food and Drug Administration (FDA) are some of the agencies of the PHS.
PubMed’s grant number search field includes research grant numbers, contract numbers, or both that designate financial support by agencies of the US PHS, and other national or international funding sources. The four parts of the grant data are:
1. The number itself, e.g., LM05545
2. The PHS 2-character grant abbreviation, e.g., LM
3. The institute acronym, e.g., NLM NIH HHS
4. The country, e.g., United States
Each individual grant part can be searched using the search field tag [gr], e.g., NIH[gr]. Note: This particular search retrieves over 1,778,000 results.
PubMed has a searchable list of grant codes and agency abbreviations used in grant numbers for you.
Another way to find information on research funded by a particular Federal grant is to use the NIH Research Portfolio Online Reporting Tools (RePORT). Federal grant numbers may be used here to search for: investigators, institutions, funding amounts, results (ie, publications), clinical studies, and more.
