XGBoost model comprehensive analysis. (a) DCA curve of the XGBoost model for the validation set. The black dotted line represents the assumption that all patients have SIRS, while the red dotted line indicates the assumption that no patients have SIRS. The remaining solid line corresponds to the XGBoost model. (b) Calibration curve of the XGBoost model for the validation set. The diagonal dashed line serves as a reference line, while the smooth solid line represents the fitted line of the XGBoost model. The closer the fitted line is to the reference line, the more accurate the model’s predictions are.
