Relative Citation Ratio (RCR): A New Metric That Uses Citation Rates to Measure Influence at the Article Level
(A) Bar graph showing the percentage of papers that experience a drop in RCR from 2012 to 2014. Black bars, decrease in RCR; grey bars, decrease in RCR of 0.1 or more. (B) Box-and-whisker plots showing the distribution of RCR values for articles describing the human microbiome, published with support from the Human Microbiome Project (HMP) of the NIH Common Fund or another source (other). Boxes show the 25th–75th percentiles with a line at the median; whiskers extend to the 10th and 90th percentiles.
