Independent correlates of mild-to-moderate isolated pulmonary hypertension
| Variable | Adjusted odds ratio | 95% CI | p-value |
| FEV1 per 1% increase from mean value for cohort | 0.99 | 0.990–0.997 | 0.006 |
| Ppcw per 1 mmHg increase above mean value for cohort | 1.22 | 1.18–1.26 | <0.001 |
| Need for assistance with ADLs | 1.24 | 1.00–1.54 | 0.047 |
| Hypertension | 1.33 | 1.03–1.72 | 0.030 |
| O2 need >3 L·min−1 | 2.84 | 2.30–3.50 | <0.001 |
CI: confidence interval; FEV1: forced expiratory volume in one second; Ppcw: pulmonary capillary wedge pressure; ADLs: activities of daily living. The Hosmer–Lemeshow Goodness-of-Fit test yields a Chi-squared value of 18.1 (p = 0.02). n = 1,883. 1 kPa = 0.133 mmHg.
