The first row represents traditional risk factors with each subsequent row demonstrating the improved predictive value of models that consider the listed parameters relative to the model with only traditional risk factors. AUC, Area under the curve; SE, Standard Error; TRF, Traditional Risk Factors; LA, Left Atrium; EF, Emptying Fraction.
