p < 0.05 Statistically significant age differences were observed between II genotypes with an ApoE4 allele and IV/VV genotypes with no ApoE4 allele.
No significant differences were observed on age (p = .182) or gender (p = .643) between CETP groups, negative for an ApoE4 allele.
Hypertension was determined by computing the average blood pressure measured across three time points. Participants were categorized as “hypertensive” based on systolic blood pressure ≥140 or diastolic blood pressure ≥90.
Cholesterol was evaluated via self-report questionnaires.
Data were unavailable for seven participants. The percentage of individuals on statins and antidepressants was determined from lists of self-reported medication use provided on the demographic questionnaires.
