Furthermore, the ROC curve in Figure 4 suggested that serum eotaxin (AUC = 0.729, P < 0.001) and RANTES (AUC = 0.776, P < 0.001) showed stronger ability than serum IL-17A (AUC = 0.617, P = 0.027) in predicting CRSwNP recurrence. This evidence concerns the gene CCL5 and chronic rhinosinusitis with nasal polyps.
