  1. Abbreviation: hs-CRP high-sensitive C-reactive protein, OR odds ratio, CI confidence interval
  2. aQuartiles of hs-CRP were created based on controls in the whole population
  3. bLinear trend was tested by using the median level of each quartile of hs-CRP as continuous variables
  4. Model 1: adjusted for age (continuous variable), matched on age (±3 years), sex, dialect, and date of blood collection (±6 months)
  5. Model 2: model 1 plus education level, smoking status, alcohol intake, physical activity, hypertension, and fasting status
  6. Model 3: model 2 plus adjusted for body mass index (continuous)
  7. Model 4: model 3 plus plasma triglycerides and HDL-cholesterol levels (both in quartiles)
