METTL3 and hepatocellular carcinoma: As a result, we found that rs1263790 in methyltransferase like 3 (METTL3) and rs57884102 in adenosine deaminase RNA‐specific B1 (ADARB1) were associated with OS of HBV‐HCC patients (HR = 0.68, 95% CI = 0.52–0.89, p = 0.004 for rs1263790 and HR = 1.70, 95% CI = 1.33–2.18, p < 0.001 for rs57884102, in combined dataset, Table 1).
