Kaplan–Meier estimates of the survival for patients using the three-gene signature. A, F Three-gene signature risk score distribution in the training and validation datasets. The black dotted line represents the median three-gene signature risk score cutoff dividing patients into low-risk and high-risk groups. B, G GC patients’ survival status in the training and validation datasets. C, H Heatmap of the three gene expression profiles in the training and validation datasets. Rows represent genes, and columns represent patients. Red: high expression; Blue: low expression. D, I Kaplan–Meier analysis for the overall survival of GC patients in the training and validation datasets. E, J The ROC curves for predicting OS in GC patients by the three-gene signature risk score
