Mixed effects multivariable logistic regression model for the outcome of mortality after mitral valve operations: modeled covariates include all high-risk criteria; model performance characteristics (C statistic = 0.78, PseudoR2 = 0.18).

CI = confidence interval; EF = ejection fraction; MR = mitral regurgitation; PROM = Predicted Risk of Mortality; STS = The Society of Thoracic Surgeons.
