Data represent as mean ± SD or number (%). *, P<0.05 for comparison with “Removed patients” (independent sample t-test or Mann-Whitney rank sum test and Chi-square test or Fisher’s exact tests for two samples testing). BMI, body mass index, BMI = Weight (Kg) ÷ Height2 (m2); ICS, inhaled corticosteroids.
