This document presents a methodology checklist for studies of diagnostic accuracy based on the work of the QUADAS2 team at Bristol University. The checklist consists of 4 domains to assess risk of bias and applicability: 1) patient selection, 2) index test, 3) reference standard, and 4) flow and timing. Each domain contains criteria to determine if a study has introduced bias or is applicable to the diagnostic accuracy question. The overall quality of studies should be assessed as high, acceptable, or unacceptable based on how many criteria are met.
