Fig 1.
Receiver operating characteristic (ROC) curves of canal paresis (CP) on the lesion side according to magnetic resonance imaging (MRI).
The ROC curves of the CP were plotted according to the patient group, as discriminated by MRI (idiopathic vs. secondary). The area under the curve for CP was 0.695, and the cut-off value was 34.5% (sensitivity 65.2%, specificity 67%).

Comparison data between the idiopathic and secondary groups.

MRI findings of intra-labyinthine hemorrhage (A,B) and labyrinthis (C,D). Labyrinthitis and intra-labyrinthine hemorrhage (ILH) both show a high signal intensity on a 3D fluid-attenuated inversion recovery sequence (B,D), but the high signal intensity on the precontrast T1 sequence suggests labyrinthine hemorrhage (A) rather than labyrinthitis (C).

Hearing recovery between the two groups after propensity matching.
Fig 3.
Cumulative partial response rates of patients with normal MRI findings (broken line) and those with an ILH or labyrinthitis (solid line) after propensity score matching.
The hazard ratio of a poor response for patients with ILH or labyrinthitis was 1.606 (95% confidence interval: 1.03–2.50).
