Relative Citation Ratio (RCR): A New Metric That Uses Citation Rates to Measure Influence at the Article Level

Fig 5

iCite, a publicly available tool for calculating RCR and accessing related citation information.

(A) Screenshot of a sample iCite result. Four hundred sample PMIDs from papers published over a 4-y window were entered into the iCite tool, which returned the maximum, mean +/− standard error of the mean (SEM), and median values for both CPY and RCR; weighted RCR is equal to the sum of the RCRs for this group. The box-and-whisker plot shows the distribution of article RCRs; bar graphs show the number of publications per year and weighted RCR per year, respectively. (B) Sample data download for an iCite result. iCite returns the total number of citations, number of CPY, expected CPY based on an NIH benchmark, FCR, Relative Citation Ratio, and percentile ranking in a downloadable Excel format for each PMID entered, as well as the corresponding title, author information, and year/journal of publication.
