Significance of Exhaled Nitric Oxide and Carbon Monoxide in Auxiliary Diagnosis and Evaluation of Allergic Rhinitis

<div>ROC curve of the nNO, eNO, and eCO levels for AR diagnosis. The AUC of the three indicators is all higher than 50%, which proved that the three indicators are both valuable in the detection of AR. The AUC of nNO is 97.8%, which is close to 100%. It shows that nNO has high value in AR detection.</div>
