GPT and infection: Compared to the GG genotype of rs35440472, a significantly higher of infection was associated with the A allele in the following subgroups: age <50 years (adjusted OR: 1.417, 95% CI: 1.181–1.699, P<0.001), the male subgroup (adjusted OR: 1.378, 95% CI: 1.144–1.659, P = 0.001), ALT < 40 (adjusted OR: 1.348, 95% CI: 1.135–1.602, P = 0.001), ALT ≥ 40 (adjusted OR: 1.503, 95% CI: 1.028–2.197, P = 0.035), AST < 40 (adjusted OR: 1.392, 95% CI: 1.180–1.641, P<0.001), and IVDU (adjusted OR: 1.399, 95% CI: 1.145–1.710, P = 0.008).
