FIG. 1. All-cause mortality vs. ApoE4 carrier status.

FIG. 1

Wilcoxon (Breslow) test of equality of survivor function indicated significant differences: χ2 (d.f.=1)= 6.55, p=0.0105.

Cox PH model controlling for dementia and MCI status (time-dependent), sex, first-visit age, race, education, smoking status (time-dependent) and first-visit BMI yielded a hazard ratio for ApoE4 carrier vs. ApoE4 non-carrier status of 1.31 with a 95% CI: 1.02–1.68, p=0.032.
