Notes: All values presented as Spearman correlation coefficient rs (p-value).Abbreviations: 6MWD, 6-minute walk distance; ∆comp, change between baseline and completion of pulmonary rehabilitation; ∆3M, change between baseline and 3 months post-program completion; ∆comp-∆3M, change between program completion and 3 months post-completion; Rmean, mean resistance; Rinsp, inspiratory resistance; Xmean, mean reactance; Xinsp, inspiratory reactance; DeltaXrs = expiratory flow limitation index.
