Data are presented as mean±sd or n (%), unless otherwise stated. FEV1: forced expiratory volume in 1 s; % pred: % predicted; FVC: forced vital capacity, IC: inspiratory capacity; MVV: maximal voluntary ventilation; TLC: total lung capacity, DLCO: carbon monoxide diffusing capacity; DL/VA: carbon monoxide diffusing capacity by alveolar ventilation coefficient; MRC: Medical Research Council Breathlessness Scale.
