Table 1.

Mean (standard deviation) and significance levels for main effects of demographic and cognitive variables for older, non-demented subjects divided on stress level and APOE-ε4 status.

	GROUPS				p-value
	High Stress		Low Stress
	ε4-pos	ε4-neg	ε4-pos	ε4-neg	Stress	APOE
	n=15	n=26	n=14	n=29
Age (Yrs)	75.8 (4.7)	80.1 (6.3)	76.8 (8.2)	79.1 (4.8)	ns	.02
Education (Yrs)	15.2 (2.4)	16.2 (2.7)	14.4 (2.8)	16.1 (3.6)	ns	ns
Mattis DRS Total	135.3 (6.6)	138.4 (3.5)	137.9 (5.0)	137.3 (4.4)	ns	ns

DRS = Dementia Rating Scale

ε4-pos = ε4-positive

ε4-neg = ε4-negative

ns = non-significant
