Development and validation of machine learning models for esophagogastric variceal bleeding risk in hepatocellular carcinoma patients

Figure 6 support vector machine model interpretable analysis SHapley Additive exPlanation plot. A: Feature importance bar chart; B: Swarm plot. The X-axis represents SHapley Additive exPlanation values, with positive values indicating an increased probability of esophagogastric variceal bleeding and negative values indicating a decreased probability. Dot colors represent feature values, ranging from low (blue) to high (red). Albumin, splenic vein diameter, and tumor burden score are continuous variables, while ascites is a binary variable. SHAP: SHapley Additive exPlanation.
