  • #: defined as mean pulmonary artery pressure >40 mmHg. CI: confidence interval; PCO2: carbon dioxide tension; FEV1: forced expiratory volume in one second; Ppcw: pulmonary capillary wedge pressure. The Hosmer–Lemeshow Goodness-of-Fit test yields a Chi-squared value of 7.2 (p = 0.51). n = 1,594. 1 kPa = 0.133 mmHg.
