  1. Values are means ± SD or numbers (%). DLCO, diffusing capacity for carbon monoxide, FEF25-75%, forced expiratory flow during the middle half of the FVC; FEV1, forced expiratory volume in 1 second; FVC, forced vital capacity; MEP, maximal expiratory pressure; MIP, maximal inspiratory pressure; Raw, airway resistance; RV, residual volume; TLC, total lung capacity; VA, alveolar volume.
