Data are presented as n (%), mean±sd or median (range). DL,CO: diffusing capacity of the lung for carbon monoxide; % pred: % predicted; FVC: forced vital capacity; TLC: total lung capacity; Pa,O2: arterial oxygen tension; Sp,O2: arterial oxygen saturation measured by pulse oximetry; RVSP: right ventricular systolic pressure; RAP: right arterial pressure. #: n = 55; +: n = 63. *: p<0.05 (unpaired t-test); ¶: p<0.05 (Wilcoxon's rank sum test).
