Source data for the diagnostic performance of delayed post gadolinium MRI descriptors across the range of MD clinical classifications

Case-controlled studies documenting the diagnostic performance of delayed post gadolinium MRI descriptors in distinguishing MD ears from asymptomatic ears or ears with other audio-vestibular conditions were identified (MEDLINE, EMBASE, Web of Science, Scopus databases: updated 17/2/2022). The meta-analysis included 66 unique studies and 3073 ears with MD, evaluating 11 MRI descriptors (in columns). The additional sheets pertain to the meta-regression. a)clinical classifications b) control group type (asymptomatic ear contralateral to MD v asymptomatic ears in other subjects v ear with other audio-vestibular condition) c) route of gadolinium administration (IV v IT) d) number of image reviewers (single v multiple observers) e) analysed on an ear basis v patient basis f) depiction of bone signal (intermediate v low) g) low risk of bias (any domain vs none) and high applicability (any vs none) h) study design (prospective v other and consecutive recruitment v other).
