From: Airway resistance at maximum inhalation as a marker of asthma and airway hyperresponsiveness
Receiver operator characteristic curves for R min , FEV 1 , and FEF 25-75 as predictors of airway hyperreactvitiy. Receiver operator characteristic (ROC) curves for Rmin, FEV1, and FEF25-75 as predictors of airway hyperresponsiveness (PC20 < 16 mg/ml). The thresholds yielding the highest combined sensitivity and specificity were 115, 91, and 82 for Rmin % predicted, FEV1 % predicted, and FEF25-75 % predicted, respectively. The area under the curve (AUC) was 0.85, 0.78, and 0.87 for Rmin % predicted, FEV1 % predicted, and FEF25-75 % predicted, respectively.
