A prediction model for 1- and 3-year DFS in GBC patients after surgery based on XGBoost regression. A. Regularization coefficients and feature factor screening. B. ROC curve analysis of the model’s predictive accuracy for 1- and 3-year DFS after GBC surgery. C. DCA of the clinical value of the model in predicting 1- and 3-year DFS after GBC surgery. D. Calibration curve analysis of the model’s stability in predicting 1- and 3-year DFS after GBC surgery. Note: XGBoost, Extreme Gradient Boosting; ROC, receiver operating characteristic; DCA, decision curve analysis; DFS, disease-free survival.
