Data are presented as mean ± 1 standard deviation. NS: not significant, BMI: body mass index, SS: Schwachmann score, NA: not applicable, rest: at rest, post ex.: post exercise, FEV₁: forced expiratory volume in 1 second, FVC: forced vital capacity, pO₂: arterial oxygen partial pressure, SpO₂: oxygen saturation, PASP: right ventricular systolic pressure, ΔPASP: PASP post-PASP rest.
