Predictive Value of Nasal Nitric Oxide and Serum NOS2 Levels in the Efficacy of Subcutaneous Immunotherapy in Pediatric Patients with Allergic Rhinitis

Table 5

ROC results of different parameters for early predicting SCIT efficacy.

Variables	AUC (95% CI)	value	Cut-off value	Sensitivity	Specificity
Serum NOS2 (IU/ml)	0.759 (0.645-0.873)	<0.001	5.5	84.1%	66.7%
Nasal NO (ppb)	0.716 (0.596-0.837)	0.003	681.0	65.1%	76.2%
Combined	0.787	<0.001	—	—	—

ROC: receiver operating characteristics; SCIT: subcutaneous immunotherapy; AUC: area under the curve; CI: confidence interval; ppb: parts per billion.
