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