| Factor | If PVC-derived area BSA ≤0.05: Intercept (Predicting CMR AR Fraction) |
| Description | Both variables remained independent predictors of AR fraction in multivariable modeling. The effect of missing data on the final prediction model was assessed using multiple imputation techniques.The estimated coefficients following multiple imputation were similar to those of the complete case analysis. |
| Biomarker | YES |
| Classification | A6 (clinical factor - other) |
| Association | |

| Application | diagnosis |
| Objective | We sought to identify the most accurate and practical method of quantifying AR severity by echocardiography in a group of patients with CHD, using CMR as a reference standard. Both variables remained independent predictors of AR fraction in multivariable modeling. |
| p Value | <0.0001 |
| Conclusion | Both variables remained independent predictors of AR fraction in multivariable modeling. The effect of missing data on the final prediction model was assessed using multiple imputation techniques.The estimated coefficients following multiple imputation were similar to those of the complete case analysis. |
