Eyes closed trial 1: all subjects ROC, sensitivity and specificity by age groups for the third eyes-closed trial. Recommended cut-points are given as the number of correct tandem steps. Without BPPV the sample size for patients is smaller and ROC values are different. See ROC no BPPV for comparison.
