ROC curves for predicting anti-asthma response in mild CA patients (A) and CVA patients (B). (A) AUCΔFEV1 = 0.827 (95% CI, 0.649 to 0.938; p < 0.001, compared with AUC0.5); AUCΔFEV1% = 0.823 (95% CI, 0.644 to 0.936; p < 0.001, compared with AUC0.5). AUCΔMEF50 = 0.812 (95% CI, 0.631 to 0.929; p < 0.01, compared with AUC0.5); AUCΔMEF50% = 0.800 (95% CI, 0.618 to 0.921; p < 0.01, compared with AUC0.5)(B) AUCFENO = 0.911 (95% CI, 0.765 to 0.980; p < 0.001, compared with AUC0.5); AUCΔFEV1 = 0.842 (95% CI, 0.679 to 0.943; p < 0.001, compared with AUC0.5); AUCΔFEV1% = 0.806 (95% CI, 0.638 to 0.920; p < 0.001, compared with AUC0.5). Abbreviations: ROC, receiver operating characteristic; AUC, area under the curve; ΔMEF50: increase of forced expiratory flow at 50% of forced vital capacity in one second in BDT; ΔMEF50%: increase of forced expiratory flow at 75% of forced vital capacity as a percentage of baseline value in BDT; FENO, fractional exhaled nitric oxide; ∆FEV1: increase of forced expiratory volume in one second in BDT; ∆FEV1%: increase of forced expiratory volume in one second as a percentage of baseline value in BDT
