Figure 3. ROC curve analysis revealed moderate accuracy of the risk model in prognosis prediction. (A) Accuracy of the risk model in predicting the overall survival of GC patients. (B) Accuracy of the risk model in predicting 1-, 2-, and 3-year overall survival of GC patients. (C) Comparison of the prediction accuracy of the risk model with clinicopathological features, such as age, sex, and pathological grading.
