Prognostic and biological role of the N-Myc downstream-regulated gene family in hepatocellular carcinoma

Figure 3 The prognostic values of the N-Myc downstream-regulated gene family genes-based signature in The Cancer Genome Atlas cohort. A: Distribution of risk scores (top); survival status (middle); gene expression of N-Myc downstream-regulated gene (NDRG)1-3 between low- and high-risk groups (bottom) in The Cancer Genome Atlas cohort; B: Kaplan–Meier overall survival analysis of low and high-risk groups; C: Comparison of gene expression between low and high-risk groups for NDRG1, NDRG2, and NDRG3; D: Receiver operating characteristic curve analysis of the association between NDRG-based signature and 1-, 2-, and 3-year overall survival probability.
