Comparative Effectiveness of Nonoperative and Operative Treatments for Rotator Cuff Tears

Slide: 3 of 38

Overview (2)

Data sources: Twelve electronic databases (1990 to September 2009), grey literature, trial registries, and reference lists were searched.

Study selection: Controlled and uncontrolled studies that assessed nonoperative or operative treatments or postoperative rehabilitation for adults with confirmed rotator cuff tears were included. Operative studies in English-language publications and nonoperative and postoperative rehabilitation studies in English, French, or German were considered. Studies were assessed in duplicate.

Data extraction: Two reviewers assessed risk for bias by using the Cochrane tool and the Newcastle–Ottawa scale. One reviewer rated the evidence by using a modified GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach. Data were extracted by one reviewer and verified by another.
