ApoE effects on the longitudinal changes (i.e., calculated difference between 2007–2011) of 44/228 (p < 0.05 after false discovery rate correction) NMR-based serum metabolic measures in all subjects participated in both follow-ups (n = 1734). Statistics: Regression models are adjusted for age, sex, baseline BMI and BMI-change. Regression β-coefficients (x-axis) indicate in standard deviation (SD) units the difference of metabolite level change between two apoE genotype subgroups (ε4− and ε4+). ε4− group is set at the origin (zero SD) and post-hoc compared with ε4+ group (circles). β-values with 95% CI are scaled to SD increments from normalized i.e., ln-transformed metabolic change measures. For clarity of illustration, only the results of the analyses with p < 0.05 after false discovery rate correction are shown here. Definitions: apoE ε4− subgroup (ε2/2, ε3/2, ε3/3 combined; n = 1112) and apoE ε4+ subgroup (ε4/2, ε4/3, ε4/4 combined; n = 622).
