SN sensitivity, SP specificity, PPV positive predictive value, NPV negative predictive value, CI confidence interval, COM chronic otitis media, AIED/AID autoimmune/autoinflammatory inner ear disease.
aThe first decision-making tree used two nodes for the amount of effusion and presence of inner ear enhancement on post-contrast T1-weighted image.
bThe second decision-making tree used two nodes of the degree of inner ear enhancement on post-contrast fluid-attenuated inversion recovery image.
