Receiver operating characteristic curves of the logistic regression models (a: cutoff value = 0.374, sensitivity = 60.5%, specificity = 66.2%; b: cutoff value = 0.370, sensitivity = 65.6%, specificity = 58.5%; c: cutoff value = 0.406, sensitivity = 62.2%, specificity = 73.9%). Separated model I (blue line): the logistic regression models to test the predictive value of the fraction of exhaled nitric oxide; separated model II (green line): the logistic regression models to test the predictive value of the fraction of exhaled carbon monoxide; integrated model (red line): the logistic regression models to test the predictive value of the fractions of exhaled nitric oxide and carbon monoxide).
