Validation of the anoikis-related prognostic signature. The distribution and scatter diagrams (top) represented the Risk score of each OV patient, referring to corresponding survival time (days), and survival status, in the TCGA-OV training cohort (A) and ICGC-OV validation cohort (B). The heatmaps (bottom) showed gene expression of the 2-gene signature (AKT2 and DAPK1) between low-risk and high-risk groups. The overall survival (OS) Kaplan–Meier (K-M) curves for patients in the TCGA-OV (C) and ICGC-OV cohort (D), which were classified into the low-risk and high-risk groups based on the anoikis-related prognostic signature. The ROC analysis of the anoikis-related prognostic signature among the TCGA-OV training cohort (E) and ICGC-OV validation cohort (F)
