^*The models include predictors prior to evaluation of a race-era interaction. Hazard ratios for the demographic and clinical variables are for the model with era as a continuous (linear) variable. HR (hazard ratio), CI (confidence interval), CHD (congenital heart disease), CMP (cardiomyopathy), ECMO (extra-corporeal membrane oxygenation)
