Model performance in the development and validation cohort. Different predictive models were generated using logistic regression (green), lasso regression analysis (yellow) or random forests (blue) for 28-day and 1-year survival. Models were trained in the development cohort and tested in the validation cohort. The discriminative performance was evaluated with the c-statistic (error bars reflect the 95% confidence interval). Model discrimination declined from the development to the validation cohort and improved from predicting 28-day to 1-year survival
