Multivariate logistic regression analysis for AD^a

Parameter	OR (95% CI)	P Value
Age (per 1-yr increase)	0.99 (0.96–1.02)	.400
Female sex	0.88 (0.55–1.41)	.593
Education (per 1-yr increase)	1.72 (0.43–7.02)	.448
Lacunar infarcts	0.46 (0.25–0.81)	.007
cSS	2.99 (0.88–12.0)	.080

^aThe model was adjusted for age, sex, length of education, and variables that showed a relationship to AD in a backward stepwise selection method.
