For hemorrhages/microbleeds, there was no significant association with age in non-carriers (PRR = 1.00, p = 0.68), but in APOE ε4 carriers, increasing age was associated with a higher prevalence of hemorrhages/microbleeds (PRR = 1.02, 95% CI 1.01–1.04, p = 0.002). The gene discussed is APOE; the disease is hemorrhage.
