Preoperative prediction of textbook outcome in intrahepatic cholangiocarcinoma by interpretable machine learning: A multicenter cohort study

Figure 5 Diagram of variable interaction. A: Hepatitis B; B: Eastern Cooperative Oncology Group score; C: Child-Pugh classification; D: Tumor size. Different features interact with each other to predict the textbook outcome (TO). For example: In hepatitis B-negative patients, the smaller the tumor, the higher the SHapley Additive exPlanations value, indicating that in hepatitis B-negative patients, the smaller the tumor, the easier it is to achieve the TO. ECOG score: Eastern Cooperative Oncology Group score; SHAP: The SHapley Additive exPlanations.
