Research Impact Metrics

Relative Citation Ratio

The Relative Citation Ratio (RCR) is a new metric, recently endorsed by the National Institutes of Health. It is based on weighting the number of citations a paper receives to a comparison group within the same field.

The iCite tool may be used to generate RCR metrics for articles with PubMed IDs.
