Model 1 was adjusted for age (years), sex (men, women) and education (≤ high school, > high school). Model 2 was model 1 additionally adjusted for prevalent hypertension (no, yes), total plasma cholesterol (mg/dL) and use of lipid lowering medication (no, yes)
b We normalized the spectral vector to the total spectral area excluding residual water signals to minimize the effects of variable dilution of the sample. The metabolic content is therefore expressed in relative metabolic content (unitless)
