This lesson is part of an introductory series developed by Cochrane Screening & Diagnostic Test Methods Group to support authors in the production of DTA reviews. A full list of currently available or planned lessons is available here.
This lesson outlines the components of quality assessment of DTA studies and explains the rationale for undertaking quality assessment. It describes the structure of the QUADAS-2 tool and provides illustrative examples of how the tool may be tailored to a review question. Finally, the lesson identifies key issues to be considered when presenting the results of quality assessment in a test accuracy review.
