After controlling for possible confounders such as sex, age, area of residence, smoking status, alcohol, BMI, history of diabetes, coffee consumption, serum ALT levels, hepatitis virus infection status B (HBsAg) and C (HCV), moderate (3–4 cups daily vs less than 3 cups; HR: 1.62; 95% CI: 0.97–2.69) and high consumption of green tea (5 cups or more daily; HR: 1.44; 95% CI: 0.84–2.45, p trend = 0.108 ) was associated with an increased risk for liver cancer, although it did not reach statistical significance.
