A prediction model for 1- and 3-year DFS in GBC patients after surgery based on LASSO regression. A, B. Regularization coefficients and feature factor screening. C. ROC curve analysis of the model’s predictive accuracy for 1- and 3-year DFS after GBC surgery. D. DCA of the clinical value of the model in predicting 1- and 3-year DFS after GBC surgery. E. Calibration curve analysis of the model’s stability in predicting 1- and 3-year DFS after GBC surgery. Note: CA199, carbohydrate antigen 199; LASSO, Least Absolute Shrinkage and Selection Operator; ROC, receiver operating characteristic; DCA, decision curve analysis; DFS, disease-free survival.
