Problem(s) |
Undocumented or unjustified deviations to the review protocol |
Number of systematic reviews included | 47 |
Summary of Findings | 91% of reviews had at least one section that had undergone a major change compared with the most recently published protocol. The greatest variation between protocols and reviews was in the methods section in which 68% of reviews had undergone a major change. The authors highlight that changes made to the protocol that could have been based on prior knowledge of the results are of most concern. |
