Logistic regression models for dementia

Model 1 Model 2 Model 3
Age 1.16
(1.12–1.20)		 1.16
(1.12–1.20)		 1.17
(1.13–1.22)
Education 0.90
(0.87–0.94)		 0.92
(0.88–0.97)		 0.91
(0.87–0.96)
Sexa 1.26
(0.88–1.80)		 1.22
(0.84–1.76)		 1.27
(0.87–1.84)
Raceb 1.66
(0.94–2.94)		 1.38
(0.78–2.45)
Any APOE ε4c 2.56
(1.71–3.82)
Wald χ2 3.07(1) 21.12(1)
p value 0.08 <0.001

Results are OR, with 95% CI in parentheses. Wald χ2 compares the fit of the model to the prior model. Significant p values indicate a significant improvement in model fit.

a

Male = 0, Female = 1.

b

Caucasian = 0, African American = 1.

c

Any APOEε4 = 1.
