Similarly, the XRCC1 Arg194Trp was not related to susceptibility to HCC under the Arg194Trp homozygous genetic model (OR = 1.13, 95% CI: 0.90–1.41, Pheterogeneity = 0.34), recessive genetic model (OR = 1.02, 95% CI: 0.82–1.26, Pheterogeneity = 0.05), dominant genetic model (OR = 1.14, 95% CI: 1.01–1.29, Pheterogeneity < 0.05), or heterozygous genetic model (OR = 1.42, 95% CI: 1.24–1.62, Pheterogeneity < 0.05). The gene discussed is XRCC1; the disease is hepatocellular carcinoma.
