Figure 1. APOE4 risk is greater in women.

Figure 1

Compared to background risk in APOE3 homozygotes, female APOE3/4 heterozygotes’ odds ratio peaks near 4 whereas the odds ratio in male APOE3/4 heterozygotes barely exceeds 1. The odds ratio for both men and women APOE4 homozygotes peaks near 10 though remains somewhat higher in women. (This is adapted from Figure 2 in the meta-analysis by Farrer and colleagues).
