Calibration curves of the logistic regression and XGBoost models for MAKE30 (A) and 90-day adverse outcomes (B) in the test set. The Brier scores of the null model, logistic regression model, and XGBoost model for MAKE30 were 0.239, 0.144, and 0.141, respectively. The Brier scores of the null model, logistic regression model, and XGBoost model for 90-day adverse outcomes were 0.088, 0.074, and 0.065, respectively.
