  • *P values for categorical variables were obtained from χ2 test (sex, indigenous ethnicity, residence and heavy alcohol consumption) or exact test (occupation, HBsAg and HCV status), and for the continuous variables Wilcoxon test (AFB1-lysine) or t-test (age).

  • †Categories do not sum to the total due to missing data.

  • AFB1, aflatoxin B1; anti-HCV, antibody to hepatitis C virus; HBsAg, hepatitis B surface antigen; HCV, hepatitis C virus.
