QUADAS-C as an optional risk of bias tool for Cochrane Reviews of Diagnostic Test Accuracy addressing comparative questions
Cochrane's Editor-in-Chief endorsed the QUADAS-C risk of bias tool as optional for prospective authors of Cochrane Diagnostic Test Accuracy (DTA) Reviews addressing comparative questions following a recommendation from the Methods Executive and relevant experts from across Cochrane and the diagnostic field. This tool helps DTA review authors to assess the risk of bias in comparative DTA studies, i.e. studies in which two or more index tests are directly compared in terms of their accuracy performance.
