Model 1 | |||
APOE ε4 positive | 16.0 (6.5–39.3) | 16.8 (9.8–18.6) | 54.3 (30.2–97.6) |
APOE ε4 negative | 6.8 (5.1–9.1) | 8.7 (6.8–11.3) | 24.6 (18.7–32.3) |
Model 2 | |||
APOE ε4 positive | 19.4 (7.0–53.9) | 12.0 (6.9–21.0) | 44.8 (24.7–81.2) |
APOE ε4 negative | 6.6 (5.0–8.8) | 8.9 (7.0–11.4) | 24.7 (18.9–32.3) |
Results are based on negative binomial regression. Bolded results are significantly different between APOE positive and negative at 0.05. Model 1 includes APOE, Model 2 includes both APOE and amyloid pathology. For NFTs, the amyloid measure was diffuse plaque counts; amyloid density was used for NFT density; and amyloid burden was used for tau burden. All models were adjusted for age at death and sex.
