Receiver operating characteristic (ROC) curves displaying the ability of various cVEMP statistics to separate Meniere’s from normal ears. Each panel shows the sensitivity of detecting Meniere’s disease (the true-positive rate) versus the false-positive rate (1 - specificity) for 500, 750 and 1000 Hz data at 123 dB peSPL. Top-row ROC statistics are threshold, normalized peak-to-peak amplitude (VEMPn) and VEMP inhibition depth (VEMPid). Bottom-row ROC statistics are 500/1000 Hz threshold ratio, VEMPn 500/1000 Hz ratio and ROCs created by combinations of the top-row metrics. Because the 500 Hz top-row data yielded the largest AUCs, this frequency was used to evaluate combinations of these metrics (bottom right panel). In each panel, the area under the curve (AUC) and 95% confidence interval (CI) of each line are displayed.
