Pain management in patients with hepatocellular carcinoma after transcatheter arterial chemoembolisation: A retrospective study

Figure 3 Predictive model visualization based on machine learning-based algorithm. A: Random forest model; B: Decision tree model. The candidate factors associated with fracture risk were ordered via random forest algorithm (A) and (B) prediction node and weight were allocated via decision tree algorithm.
