Observed vs. predicted cumulative incidence curves for sudden death by tertile of the risk scores based on the sudden death models in I-Preserve. a Sudden death model 1, b sudden death model 2, c sudden death model 3, d sudden death model 4. Red solid lines are predicted cumulative incidence curves based on the corresponding models, and black dotted lines are the observed cumulative incidence curves based on Aalen–Johansen estimators
