Flawed risk of bias undertaken Weaknesses identified in some Cochrane reviews |
Number of systematic reviews included | 718 |
Summary of Findings | 26% of judgements regarding included trials for performance bias were not in line with the Cochrane Handbook and were therefore considered inadequate. Particularly high number of discrepancies when Cochrane authors judged the risk as low, mostly because Cochrane authors accepted statements such as ‘‘double blind’’ and ‘‘placebo’’ as sufficient proof for this domain. |
