In the adjusted model II, the hazard ratios (95%CI) for the recurrence of HCC with staging I–II across GLR tertiles were as follows: The low tertile: < 20.442 (1.0), the middle tertile: 20.442–50.382 (1.748 (1.170–2.612)), the high tertile: > 50.382 (2.078 (1.339–3.227)), independent of age, sex, smoking, operation time, lymphovascular invasion, allogeneic blood, HB, AST, ALP, HBsAg, tumor number, tumor size, AFP. Here, GSTM1 is linked to hepatocellular carcinoma.
