Stratified GEE Models examining the influence of ε4 for rate of decline in the Incident sample

Stratification Sample	n	Beta	p
Young (< 82)	101	−.05	.08
Old (>= 82)	98	−.07	.05
Women	146	−.07	<.01
Men	53	−.01	.87
Hispanic	121	−.07	.01
African American	61	−.02	.68
Caucasian	15	−.52	<.01
Low Education (<= 6)	105	−.04	.14
High Education (> 6)	93	−.11	<.01

Note. Beta values represent the rate of change over time as a function of ε4 status. Age and education groups were based on a median split. Models within a demographic category included the remaining demographic variables as covariates.
