Data are expressed as odds ratio (95% confidence interval) with references of highest quartiles (Q1). Model 1: unadjusted; Model 2: adjusted for age, sex, height, and current smoking (versus nonsmokers); Model 3: Model 2 plus adjustment for daily alcohol consumption (versus infrequent/no alcohol consumption), regular exercise (versus no regular exercise), waist circumference, log-transformed CRP, and self-reported past history of stroke; Model 4: Model 3 plus adjustment for diabetes; Model 5: Model 3 plus adjustment for MetS.
*
P values correspond to tests for linear trends across quartile treated as a continuous value. †, § for each association.
