DOM, domain; DOM1A1, consecutive or random sample of patients enrolled; DOM1A2, case–control design avoided; DOM1A3, study avoided inappropriate exclusions; DOM1A4, selection of patients introduced bias; DOM1B, concern that included patients do not match the review question; DOM2A1, index test results interpreted without knowledge of results of reference standard; DOM2A2, prespecified threshold used; DOM2A3, could the conduct of index test have introduced bias; Dom2B, concern that index test conduct or interpretation differ from review question; DOM3A1, reference standard correctly classifies condition; DOM3A2, reference standard results interpreted independently from index test results; DOM3A3, could the reference standard, its conduct, or its interpretation have introduced bias; DOM3B, concern that target condition defined by reference standard does not match review question; DOM4A1, appropriate interval between index test and reference standard; DOM4A2, all patients received the reference standard; DOM4A3, patients received the same reference standard; DOM4A4, all patients included in the analysis; DOM4A5, could the patient flow have introduced bias; H, high; L, low; N, no; U, unclear; Y, yes.
