Note: Presented in the table are the numbers of simulations where the model computed did not produce constant predictions nor predicted survival probabilities equal to 1. Scenario 1 candidate predictors include clinical variables and biomarkers. Scenario 2 candidate predictors include clinical variables, biomarkers, and genetic variants. BE, backward elimination; EPV, events per variable.
