As shown in Table 4, in the additive genetic model, HBV‐HCC patients with the METTL3 rs1263790 G allele had a favourable OS (ptrend = 0.004), and the ADARB1 rs57884102 T allele was a risk factor for HBV‐HCC OS (ptrend <0.001) in the combined dataset. This evidence concerns the gene METTL3 and hepatocellular carcinoma.
