Data are presented as mean±sd, unless otherwise stated. ES: effect size; FEV1: forced expiratory volume in 1 s; DLCO: diffusing capacity of the lung for carbon monoxide; RV: residual volume; TLC: total lung capacity; 6MWD: 6-min walk distance; SpO2: arterial oxygen saturation measured by pulse oximetry; HR: heart rate; DSP: distance–saturation product. Level of significance was set at p≤0.05; ns: nonsignificant.
