Models were adjusted for age at death, gender and presence of an apolipoprotein E *E4 allele. The maximum possible sample size in this multivariate analyses for the AD group is 60, due to the absence of apolipoprotein genotyping of one individual.
Abbreviations: NDC, non-demented control; AD, Alzheimer's disease; ACA, anterior cerebral arteries; BA, basilar artery; ICA, internal carotid arteries; MCA, middle cerebral arteries; PCA, posterior cerebral arteries; VA, vertebral arteries.
