Figure 5 Validation of the risk model in the Gene Expression Omnibus cohort. A: Distribution of patients in the Gene Expression Omnibus (GEO) cohort based on the median risk score in The Cancer Genome Atlas (TCGA) cohort; B and C: Principal component analysis (PCA) plot and t-distributed stochastic neighbor embedding (t-SNE) analysis for gastric cancer (GC) patients in the GEO cohort; D: The distributions of overall survival (OS) status, OS and risk score for each patient in the GEO cohort; E: Kaplan-Meier curves for comparison of the OS between low-risk and high-risk groups in the GEO cohort; F: Time-dependent receiver operating characteristic (ROC) curves for GC in the GEO cohort.
