Relative Citation Ratio (RCR)

rcr

relative_citation_ratio

Relative Citation Ratio (RCR)--OPA's metric of scientific influence. RCR represents the field- and time-normalized citation rate, and is benchmarked to 1.0 for a typical (median) NIH-funded paper in the corresponding year of publication. A paper with an RCR of 1.0 has received the same number of cites/year as the median NIH-funded paper in its field, a paper with an RCR of 2.0 has received twice as many cites/year as the median NIH-funded paper in its field, while an RCR of 0.5 means that it is receiving half as many citations per year. Calculation details are documented in Hutchins et al., PLoS Biol. 2016;14(9):e1002541.* Also see here for more information.

Provisional

rcrIsProvisional

provisional

RCRs for papers published in the previous two years are flagged as "provisional", to reflect that citation metrics for newer articles are not necessarily as stable as they are for older articles. Provisional RCRs are provided for papers published in the previous year if they have received 5 citations or more. All papers published the year before the previous year receive provisional RCRs. The current year is considered to be the NIH Fiscal Year which starts in October. For example, in July 2019 (NIH Fiscal Year 2019), papers from 2018 receive provisional RCRs if they have 5 citations or more, and all papers from 2017 receive provisional RCRs. In October 2019, at the start of NIH Fiscal Year 2020, papers from 2019 receive provisional RCRs if they have 5 citations or more and all papers from 2018 receive provisional RCRs. See also here.

Citations Per Year

acr

citations_per_year

Citations per year that this article has received since its publication. If this appeared as a preprint and a published article, the year from the published version is used as the primary publication date. This is the numerator for the Relative Citation Ratio.

Field Citation Rate

fcr

field_citation_rate

Measure of the intrinsic citation rate of this paper's field, estimated using its co-citation network.

Expected Citation Rate

ecr

expected_citations_per_year

Citations per year that NIH-funded articles, with the same Field Citation Rate and published in the same year as this paper, receive. This is the denominator for the Relative Citation Ratio.

NIH Percentile

nihRcrPercentile

nih_percentile

Percentile rank of this paper's RCR compared to all NIH publications. For example, 95% indicates that this paper's RCR is higher than 95% of all NIH funded publications.
