Next, the risk score of each HCC patient in the TCGA dataset was calculated using the following formula: 0.238*expression level of RAB10 + 0.609*expression level of TCOF1+0.360*expression level of PSMD14. Patients were stratified into two groups based on the risk score; patients with risk scores higher than the median value were classified in high-risk group (n = 182), whereas patients with risk scores lower than the median value were classified in low-risk group (n = 183) (Figure 2A). This evidence concerns the gene PSMD14 and hepatocellular carcinoma.
