Prognostic impact and reasons for variability by tumor location in gastric cancer

Figure 4 Variable importance of the predictors for the predictive models for gastric cancer location. A: The minimum depth method was used to calculate the influencing factors related to the location of gastric cancer (GC). The vertical dashed line represents the minimum depth threshold; B: The variable importance method was used to calculate the influencing factors related to the location of GC. The green dots indicate strong correlations among impact factors, and the orange dots indicate weak correlations among impact factors. CEA: Carcinoembryonic antigen; AFP: Alpha-fetoprotein; CA: Carbohydrate antigen; BMI: Body mass index; pTNM: Pathological tumor-node-metastasis.
