†Model 1: adjusted for age and sex.

‡Model 2: adjusted for age, sex, current smoking and severe drinking.

§Model 3: adjusted for age, sex, current smoking, severe drinking, family income, residence, hypertension, stroke, bronchial asthma, influenza vaccination, allergic rhinitis and pulmonary tuberculosis.

BMI, body mass index; CRSwNP, chronic rhinosinusitis with nasal polyps; WC, waist circumference.
