Fig. 2

This figure presents calibration plots for multiple predictive models assessing their performance in predicting (A) primary and (B) secondary outcomes in the CMUH test set. Each model's Brier score, indicating the accuracy of probabilistic predictions, is displayed along with 95% CI. The shaded areas represent the 95% CI for each model's calibration curve.
