Normally distributed data are presented as mean±sd; non-normally distributed data as median (5th–95th percentile). Significant differences are in bold. DLCO: diffusing capacity of the lung for carbon monoxide; FEV1: forced expiratory volume in 1 s; BMI: body mass index; peak V′O2: peak oxygen consumption; V′E/V′CO2 slope: ventilatory efficiency for carbon dioxide slope; resting PETCO2: pressure of end-tidal carbon dioxide at rest.
