  1. Information is given as arithmetic mean (standard error) or percentage. Differences in means or percentages by random glucose categories were assessed by F test or Rao-Scott χ2 test
  2. a no observations in this cell; p value for association excluding random glucose level ≥ 11.1 mmol/L
  3. b normal / moderate / high: < 94 / 94 - < 102 / ≥ 102 cm in men and < 80 / 80 - < 88 / ≥ 88 cm in women
  4. c mean (standard error) is given separately for men and women due to sex-specific differences in waist circumference distribution
  5. d no / moderate / high: 0 / > 0 - < 20 / ≥ 20 g/day in men and 0 / > 0 - < 10 / ≥ 10 g/day in women
