Independent correlates of mild-to-moderate pulmonary hypertension#
| Variable | Adjusted odds ratio | 95% CI | p-value |
| Need for any O2 | 1.22 | 1.14–1.30 | <0.001 |
| Ppcw per 1 mmHg increase above mean value for cohort | 1.19 | 1.16–1.21 | <0.001 |
| FEV1 per 1% increase from mean value for cohort | 0.99 | 0.99–1.00 | 0.050 |
CI: confidence interval; Ppcw: pulmonary capillary wedge pressure; FEV1: forced expiratory volume in one second. The Hosmer–Lemeshow Goodness-of-Fit test yields a Chi-squared value of 14.8 (p = 0.06). #: defined as mean pulmonary artery pressure between 25–40 mmHg. n = 2,296. 1 kPa = 0.133 mmHg.
