Clinical parameters across different hemodynamic subgroups (a) Diffusing capacity of the lung for carbon monoxide according to the alveolar volume (DLCO/VA %predicted), (b) 6-min walk distance, (c) peak oxygen consumption (VO2), (d) minute ventilation (VE) vs. peak carbon dioxide output (VCO2) slope, (e) oxygen saturation in arterial blood (SaO2) at peak exercise, (f) tricuspid annular plane systolic excursion (TAPSE)/systolic pulmonary arterial pressure (sPAP) ratio. Bars denote medians, boxes denote interquartile ranges, whiskers denote ranges excluding statistical outliers (•) (> 1.5 box lengths from either the 25th or 75th percentiles).
