β: unstandardized regression coefficients were obtained from mixed-effects regression models

Model 1 was adjusted for sex, age, education years, BMI, smoking and drinking status, diabetes, hypertension and coronary artery disease history and per se use of lipid-lowering medication and intakes of energy, protein, carbohydrates, fat, SFA, PUFA, and MUFA

Model 2 was adjusted as for model 1 and for number of APOE ε4 alleles
