Combining lymph node ratio to develop prognostic models for postoperative gastric neuroendocrine neoplasm patients

Figure 7 The SHapley Additive exPlanations plot of the random survival forest model. A dot on the SHapley Additive exPlanations plot represents a sample. Y-axis variables are sorted according to the variables’ importance. The X-axis represents the influence of variables on the model output outcome. The left side of X = 0.0 represents the negative effect of variables on the outcome, and the right side of X = 0.0 represents the positive effect of variables on the outcome. Taking lymph node ratio as an example, the higher the lymph node ratio level, the worse the prognosis of patients. LNR: Lymph node ratio; SHAP: SHapley Additive exPlanations.
