Validation of the Lasso prediction model using validation dataset. A. ROC curve analysis of the model’s predictive accuracy for 1- and 3-year DFS after GBC surgery. B, 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: LASSO, Least Absolute Shrinkage and Selection Operator; ROC, receiver operating characteristic; DCA, decision curve analysis; DFS, disease-free survival.
