New impact factors for Cochrane and Cochrane Oral Health

The 2019 Journal Citation Report (JCR) has been released by Clarivate Analytics, and we can announce that the Cochrane Database of Systematic Reviews (CDSR) Journal Impact Factor is now 7.890This is an increase on the 2018 Journal Impact Factor, which was 7.755.

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 2 years and dividing that number by the total number of Reviews published in the past 2 years. It is a useful metric for measuring the strength of a journal by how often its publications are cited in scholarly articles.

The CDSR is now ranked 10 of the 165 journals in the Medicine, General & Internal category.


Cochrane Oral Health does not have an "official" impact factor, but our publisher Wiley provides an unofficial impact factor for us. For 2019, this was 4.868 (38 publications cited 185 times). This means we are at par with the fourth most cited dental journal in the world.
