  1. Continuous variables are represented as mean (min–max). Categorical variables are represented as counts
  2. PAH: primary pulmonary arterial hypertension; FEV1: forced expiratory volume in first second; FVC: forced vital capacity; mPAP: mean pulmonary arterial pressure; PVR: pulmonary vascular resistance; PCWP: pulmonary capillary wedge pressure; 6MWD: six-minute walk distance
