| BMI | −0.01 (−0.03 to 0.01) | 0.49 |
| No. of PAH medications | 0.14 (−0.16 to 0.44) | 0.35 |
Note
Coefficient reported as mean change in predictor per log g/m2 of right ventricular mass index with 95% confidence interval (CI). mPAP: mean pulmonary artery pressure; PVR: pulmonary vascular resistance; CPA: pulmonary artery compliance; BMI: body mass index, calculated as weight in kilograms divided by the square of height in meters; PAH: pulmonary arterial hypertension.
