Characteristics of patient population baseline (BL) compared to 9-month follow-up; data is presented as Mean ± SD; group comparisons of measurements across different Randomization Groups were done using a paired student’s t-test; *statistical significance is set at P ≤ 0.05. 6MWT = 6-minute walk test; FEV₁ (%) = Forced Expiratory Volume in one second% predicted; CAT = COPD Assessment Test.
