| Summary of Findings | Review authors often specified in the risk of bias tables the study outcomes that were not reported (84 % of studies) but less frequently specified the outcomes that were partially reported (61 % of studies). At least one study was rated at high risk of outcome non-reporting bias in 31% of reviews. In the random sample of these reviews, only 30% incorporated this information when interpreting results, by acknowledging that the synthesis of an outcome was missing data that were not/partially reported. Many reasons provided by review authors for high-risk judgements were too vague in order to allow readers to understand which specific outcomes should be interpreted with caution. |
