Application of preoperative artificial neural network based on blood biomarkers and clinicopathological parameters for predicting long-term survival of patients with gastric cancer

Figure 5 Survival curves of the pathological TNM staging. A: In the training set, the survival curve discrimination between stages IA and IB was poor (P = 0.240), and there was no significant difference in the survival curves between stages IIA and IIB and IIB and IIIA (P < 0.05). B: In the testing set, there was no significant difference in survival curves between stages IA and IB, IIA and IIB, and IIIA and IIIB of the pathological TNM staging (P > 0.05). pTNM: Pathological TNM.
