The risk score of HCC patients was calculated using the following equation: risk score = (0.0262 ∗ expression level of YTHDF1) + (0.0577 ∗ expression level of YTHDF2) + (0.1192 ∗ expression level of IGF2BP3) + (0.027 ∗ expression level of KIAA1429) + (0.0795 ∗ expression level of METTL3) – (0.1018 ∗ expression level of ZC3H13). The gene discussed is VIRMA; the disease is hepatocellular carcinoma.
