CRS, chronic rhinosinusitis; ECRS, eosinophilic CRS; IgE, immunoglobulin E; F, female; FeNO, fractional exhaled nitric oxide; Local infiltrating eosinophilia (%), eosinophils/total inflammatory cells; M, male; NECRS, non‐ECRS; PBEC, peripheral blood eosinophil cell. Data are presented as mean ± SD. Statistical significance was evaluated by one‐way ANOVA, chi‐squared test, and Tukey's test.
