Figure 6. Survival curves, sample distribution and ROC curves of high- and low-risk groups. (A–F) The survival differences of different risk groups in TCGA-TRAIN, TCGA-TEST, TCGA-ALL, GEO30219, GEO30210 and GEO42127, respectively, were presented. (G–L) The PCA sample distribution of different risk groups in TCGA-TRAIN, TCGA-TEST, TCGA-ALL, GEO30219, GEO30210 and GEO42127, respectively, were presented. (M–P) The ROC curves of different risk groups in TCGA-TRAIN, GEO30219, GEO30210 and GEO42127 at 1-, 3-, 5-, 7-, and 10-years, respectively, were presented.
