Multiplicity of outcomes and lack of pre-specification for outcome reporting No registered or published protocol |
Number of systematic reviews included | 44 |
Summary of Findings | Only 48% had a publicly available protocol. Multiplicity of results was common, occurring in 49% of trial reports. Pre-specification of decision rules to select results from multiple measurement scales and intervention/control groups (in multi-arm trials) was uncommon (19% and 14% of review protocols, respectively). Overall, 70% of reviews included at least one randomized controlled trial with multiplicity of results, but this occurred less frequently in reviews with a protocol. |
