The 2021 Journal Citation Report has been released by Clarivate Analytics, and we are delighted to announce that the Journal Impact Factor for the Cochrane Database of Systematic Reviews (CDSR) is now 12.008. This is an increase on the 2020 Journal Impact Factor, which was 9.289.
The CDSR Journal Impact Factor is calculated by taking the total number of citations in a given year to all Cochrane Reviews published in the past two years and dividing that number by the total number of Reviews published in the past two years. While Journal Impact Factor is a useful measure of average citation frequency, we recognize that it is not the only measure of success or impact.
Some highlights from the CDSR 2021 Journal Citation Report:
- CDSR is ranked 19th of the 172 journals in the Medicine, General & Internal category
- CDSR received 92,845 cites in the 2021 Journal Impact Factor period, compared with 81,212 in 2020
- The 5-Year Journal Impact Factor is 11.956 compared with 9.871 in 2020
Cochrane Library’s Editor in Chief, Karla Soares-Weiser, commented: “I am delighted to see a rise in Impact Factor for the Cochrane Database of Systematic Reviews. Cochrane’s efforts to publish high quality reviews on COVID-19 have clearly made an impact, as several of these make up our top 20 cited reviews for 2021. All of these data demonstrate the continuing usage and impact of Cochrane Reviews and reflect enormous credit on our many thousands of contributors and groups.”
