Receiver operating characteristics curves were performed to derive accuracy and cutoff values for the JESREC scores of olfactory dysfunction criterion.Results: A total of 354 patients (mean [SD] age, 50.0 [14.9] years; 41.8% women) were included in the finally analysis. The prevalence of olfactory dysfunction was 46.3%. Individuals who had olfactory dysfunction were more likely to be male (64.6% vs. 52.6%), ECRS (39.0% vs. 7.9%), longer course (2.3 vs. 1.5 years), higher JESREC scores (8.5 vs. 4.5) and had higher proportion of nasal polyps (78.7% vs. 18.9%) and peripheral eosinophilia (3.3% vs. 1.4%). In logistic analysis,
