  1. ALT: alanine aminotransferase; OR: odds ratios; CI: confidence interval;
  2. *Adjusted for age, sex, ethnicity, area, education, body mass index, average salt consumption, history of diabetes, overall stress and hepatitis B surface antigen status
  3. P for trend was calculated by setting categorized ALT levels as a continuous variable
