*Statistical significances were evaluated using Mann-Whitney test, independent samples t-test or Chi-square test, respectively. Results are displayed as median (interquartile range), mean (SD), or n (%). BMI: body mass index; FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity; COPD: chronic obstructive pulmonary disease; ICS: inhaled corticosteroid; LABA: long acting beta-adrenoceptor agonist.
