Clinical Trial Summary

Background: Summary of Findings (SoF) tables have been developed to present results of systematic reviews in a concise and explicit format. Adopted by many review groups including the Cochrane Collaboration, the Agency for Healthcare Research and Quality (AHRQ), and the GRADE Working Group; SoF tables provide succinct, transparent, and easily interpretable judgments about the certainty of evidence and magnitude of effects. Currently, there are three different SoF formats in use. This study aims to compare SoF table formats in terms of understanding, accessibility, satisfaction, and preference with systematic review users.

Methods: The primary objective of this three-arm randomized control non-inferiority trial is to investigate the understanding of information presented in three different SoF tables: a new current GRADE-SoF table, a new alternative GRADE-SoF table, and EPC-SoF table with systematic review users. Researchers, clinical practice guideline developers, policy-makers, end-users, or knowledge transfer will be recruited. Data will be collected electronically at baseline and after randomization.

Discussion: This study aims to assess the understanding, accessibility, satisfaction, and preference between three SoF tables for displaying summary evidence from health-related outcomes. The results of this study will provide important knowledge to understand what information should be included in SoF tables in systematic reviews.
