Problem(s) Lack of supplementary searches beyond databases
Number of systematic reviews included 23
Summary of Findings Cumulative median recall for combined searching in MEDLINE, EMBASE and CENTRAL was 88.9% of relevant references, which increased to 90.9% when adding 10 additional databases. It is possible that searching databases is not sufficient to identify all relevant references, and that reviewers must rely upon additional sources in their literature search.
