Multivariate logistic regression analysis for identifying parameters with predictive value for PH.
| Parameters※ | Odds ratio | 95% CI | p |
|---|---|---|---|
| Excluding TR-related parameters | |||
| RVOT-AT (< 93 ms) | 10.68 | 4.16–27.45 | < 0.001 |
| mPA (> 25 mm) | 4.13 | 1.59–10.74 | 0.004 |
| RAA (> 14.5 cm2) | 3.23 | 1.22–8.56 | 0.018 |

| Indexing sPAP and TRV | |||
| RVOT-AT (< 93 ms) | 6.98 | 2.58–18.85 | < 0.001 |
| sPAP (> 37.5 mmHg) | 10.12 | 3.68–27.86 | < 0.001 |
Note: mPA, main pulmonary artery diameter.
Abbreviations: CI, confidence interval; PH, pulmonary hypertension; RAA, right atrial area; RVOT-AT, right ventricular outflow tract acceleration time; sPAP, systolic pulmonary arterial pressure; TRV, tricuspid regurgitation velocity.
※Parameters were assessed with a logistic regression model with a forward stepwise likelihood ratio.
