Data on intake and plasma level are log transformed. Adjusted for age, sex, BMI, marital status, education, current smoking, energy intake(ln), thyroid disease and vascular risk factors (hypertension, diabetes mellitus, dyslipidemia, stroke and cardiovascular disease) as covariates (*p < 0.05, **p < 0.01, ***p < 0.001).
