CAT and hepatocellular carcinoma: Patients with no history of smoking and with the rs769217 CT genotype and at least 1 copy of the T allele (dominant model) were 1.79 times and 1.76 times more likely to develop HCC compared with those carrying the CC genotype (OR = 1.79, 95% CI = 1.06–3.03, P = 0.030 and OR = 1.76, 95% CI = 1.09–2.84, P = 0.020) (see Table 3, Supplemental Content, http://links.lww.com/MD/A235, which illustrates the genotype distributions of CAT polymorphisms estimated by tobacco smoking).
