  1. Comparisons between excluded patients and those completing the study were performed using the unpaired t-test or Mann–Whitney test; p ≤ 0.05. Plus–minus values are presented as mean ± SD. Other values are presented as numbers. Definition of abbreviations: Gender F/M = gender female/male; FEV1 = forced expiratory volume in the first second (% of predicted); FVC = forced vital capacity (% of predicted); BMI = body mass index; SpO2 = pulse oximeter oxygen saturation; MMRC = Modified Medical Research Council; 6MWD = six-minute walking distance; BMI = body mass index; IL-6 = Interleukin 6; CRP = C-reactive protein.
