  • Data are presented as n or mean±sd. All values are post-bronchodilator. FEV1: forced expiratory volume in 1 s; % pred: % predicted; FVC: forced vital capacity; TLC: total lung capacity; VC: vital capacity; RV: residual volume; DLCO: diffusing capacity of the lung for carbon monoxide; MIP: maximal inspiratory mouth pressure; MEP: maximal expiratory mouth pressure; GOLD: Global Initiative for Chronic Obstructive Pulmonary Disease; BMI: body mass index.
