Supplementary Table 1 shows the number of Alzheimer’s dementia cases and cognitively unimpaired controls for each APOE genotype in (a) the Alzheimer’s Disease Genetics Consortium (ADGC’s) clinically characterized and neuropathologically confirmed autopsy group, (b) its clinically characterized but neuropathologically unconfirmed clinical group, and (c) the combined neuropathological and clinical group. Here, APOE is linked to Alzheimer disease.
