Stepwise linear regressions were conducted with cholesterol, low density lipoprotein as the dependent variable and age, sex (0 = women, 1 = men), overweight status (0 = no, 1 = yes), APOE ε2 genotype (0 = no, 1 = yes), APOE ε3 genotype (0 = no, 1 = yes), APOE ε4 genotype (0 = no, 1 = yes), atypical antipsychotic drug use (0 = no, 1 = yes), diabetes (0 = no, 1 = yes), high blood pressure (0 = no, 1 = yes), and lipid-lowering medication use (0 = no, 1 = yes) as independent variables. Here, APOE is linked to diabetes mellitus.
