Uniquely computed research metrics are available in Dimensions and include:
The Relative Citation Ratio (RCR) indicates the relative citation performance of an article, when compared to other articles in its area of research. The RCR is normalized to 1.0 and calculated for all articles funded by the NIH in the Dimensions catalog. An RCR of more than 1.0 shows that a publication has an above average citation rate for its group, when defined by the subject area citation rates of the articles that have been cited with it.
Articles that are less than 2 years old, or do not have citations, do not have an RCR.
The Field Citation Ratio (FCR) indicates the relative citation performance of an article, when compared to similarly-aged articles in its subject area. The FCR is normalized to 1.0 for this selection of articles. An FCR value of more than 1.0 shows that the publication has a higher than average number of citations for its group (defined by its FoR Subject Code, publishing year, and age).
Articles that are less than 2 years old do not have an FCR. An article with zero citations has an FCR of 0.
