Each year in June, Clarivate Analytics publishes the impact factors of all journals indexed in the Journal Citation Report. The Cochrane Database of Systematic Reviews (CDSR) impact factor describes the ratio of the number of Cochrane Reviews published during a two-year period (e.g. 2010 and 2011) to the number of citations these reviews received in the subsequent year (e.g. 2012). The CDSR received its first impact factor in 2007.
