AR, Allergic rhinitis; COPD, chronic obstructive pulmonary disease; COVID-19, coronavirus disease 2019; CRS, chronic rhinosinusitis.
Data are presented as medians and interquartile range for continuous variables and numbers with percentage for categorical variables.
A Mann-Whitney U 2-tailed test was used for between-group comparison. For categorical variables, the χ2 or Fisher's exact test was applied to compare the difference in proportions between groups when appropriate.
Bold indicates statistical signficance (P < .05).
Age, gender, smoking status, and comorbidities (hypertension, diabetes, cardiovascular disease, cerebrovascular diseases, malignancy, chronic liver diseases, chronic kidney diseases, allergic rhinitis, asthma, and chronic obstructive pulmonary disease) were selected for propensity score matching.
