Violin plot depicting the distribution of FEV₁ values at baseline and the end of the study period (week 26 ± 2). The shape of the violin plot shows the increased frequency of the corresponding FEV₁ distribution. The dots indicate the individual patients, and the bars indicate the median values. Mean FEV₁ significantly improved from baseline to week 26 (1.60, SD 0.54 L vs. 1.98, SD 0.56 L; p < 0.0001). Abbreviation: FEV₁ forced expiratory volume in 1 s
