ObjectiveTo develop a transparency evaluation tool 2.0 of clinical practice guidelines (CPGs) oriented by public trust. MethodsThe Delphi method was employed to score and select the importance and operability of evaluation indicators. The analytic hierarchy process was used to determine the weights of the indicators. And the final evaluation indicator system was determined through expert consensus meeting. ResultsIt constructed two first-level indicators including conflict of interest and formulation process, and six second-level indicators, including guideline developers, reviewers, protocol and registration, evidence production, recommendation formation, and external review. Based on the second-level indicators, a total of 21 third-level indicators were constructed from the perspectives of disclosure and management. The logical structure of the tool is rigorous and harmonious. ConclusionThe CPGs transparency assessment tool 2.0 developed in this study provides measurement standards and an evaluation framework for assessing transparency in CPGs.
