ROC curves of ALOX15, blood eosinophils, and their combination for predicting the diagnosis of ECRSwNP. The predictive ability was calculated according to AUC. ALOX15 alone and in combination with blood eosinophils demonstrated high accuracies, and blood eosinophils alone moderate accuracy in predicting ECRSwNP (AUC: 0.909, 0.933, and 0.820, respectively). ROC receiver operator characteristic, ALOX15 arachidonate 15-lipoxygenase, ECRSwNP eosinophilic chronic rhinosinusitis with nasal polyps, AUC area under the curve. ‡: combined ALOX15 with blood eosinophils
