Risk of an adverse outcome(death or lung transplantation) in relation to risk marker measurements at the time of the diagnosis
| Simple model | Multiple model | |||
| HR (95% CI) | p-value | HR (95% CI) | p-value | |
| P̄ra per 1 mmHg increase | 1.04 (0.99–1.1) | 0.075 | ||
| Cardiac index per 0.5 L·min−1·m2 decrease | 1.05 (0.99–1.1) | 0.043 | ||
| PVR per 100 dyn·s·cm−5 increase | 1.04 (1.0–1.08) | 0.024 | ||
| Sv,O2 per 5% decrease | 1.14 (1.02–1.29) | 0.026 | 1.03 (1.03–1.53) | 0.028 |
| P̄pa per 5 mmHg increase | 1.02 (0.998–1.19) | 0.056 | ||
| 6MWD per 20 m decrease | 1.12 (1.05–1.24) | 0.001 | 1.12 (1.05–1.21) | 0.001 |
| NYHA class | 1.20 (0.61–2.12) | 0.589 | ||
Estimated hazard ratios (HR), 95% confidence intervals (CI), and p-values were calculated by simple and stepwise forward Cox regression analyses. HRs refer to the indicated scales in these variables. P̄ra: mean right atrial pressure; PVR: pulmonary vascular resistance; Sv,O2: mixed venous oxygen saturation; P̄pa: mean pulmonary artery pressure; 6MWD: 6-min walk distance; NYHA: New York Heart Association.
