  1. Values are presented as mean (SD). BMI, body mass index; DLCO, diffusion capacity for carbon monoxide; FEV1, forced expiratory volume in one second; FEV1/FVC ratio, forced expiratory volume in 1 sec (FEV1) expressed as percent of FVC; MET, metabolic equivalent; PAL, physical activity level; PaCO2, partial pressure of carbon dioxide; PaO2, partial pressure of oxygen;RV/TLC, residual volume/total lung capacity ratio; TEEACC, total energy expenditure per day as assessed by accelerometry; TLC, total lung capacity.
