Significant factors that predict the risk of postoperative recurrence in ECRSwNP patients

Index	Optimum cutoff value	Sensitivity	Specificity	Jordan value	AUC	P	95% CI
Percentage of eosinophils in tissue	13.85	0.641	0.59	0.231	0.654	0.003	0.560-0.749
Serum sIGE	3.65 IU/ml	0.564	0.857	0.421	0.773	<0.001	0.684-0.862
IL-5	66.45 ng/L	0.821	0.907	0.728	0.927	<0.001	0.883-0.971
ECP	58.65 μg/L	0.564	0.708	0.272	0.680	<0.001	0.584-0.777
PH value of intraoperative flush solution	-	0.692	0.677	0.369	0.685	<0.001	0.591-0.778
Postoperative nasal environment	-	0.692	0.783	0.475	0.737	<0.001	0.645-0.829

Note: Among them, the PH value of the operative rinsing solution and the condition of the postoperative nasal internal environment were dichotomous variables. pH = 6 of the operative rinsing solution was assigned as 0 and pH = 8 as 1. The status of the postoperative nasal internal environment was assigned as 0, and the infection of the nasal internal environment as 1. ECRSwNP, eosinophilic chronic rhinosinusitis with nasal polyps; ECP, eosinophil cationic protein.
