Evaluating log odds of positive lymph nodes as a prognostic tool in differentiated gastric cancer: A retrospective study

Figure 4 Construction of a nomogram model to predict the prognosis of gastric cancer patients based on log odds of positive lymph nodes, tumor differentiation, and other independent risk factors. A: Nomogram; B: Calibration curve of the nomogram; C: Receiver operating characteristic curves for the nomogram and pathological tumor-node-metastasis staging systems; D: Kaplan–Meier curve of overall survival for the high-risk and low-risk groups based on the nomogram; E: Decision curve analysis comparing the nomogram with the pathological tumor-node-metastasis staging system. (P < 0.005). LODDS: Log odds of positive lymph nodes; CA: Carbohydrate antigen; CEA: Carcinoembryonic antigen; pTNM: Pathological tumor-node-metastasis; OS: Overall survival; ROC: Receiver operating characteristic; AUC: Area under the curve.
