Response-operating characteristic (ROC) curve analysis for discrimination between cases and controls using IL-5 AV. IL-5 AV has good discriminative value. Area under the ROC curve (AUC) = .814 (95% CI = 0.704 to 0.897, p-value < .001). Best cut-off criterion > 5.0% (sensitivity = 64%, specificity = 90%, J-index = .54)
