Table.

Multivariate logistic regression analysis of subjective memory complaint testing the simultaneous influence of GDS score and salivary cortisol measures (Post-peak cortisol, CAR slope) after controlling for gender, CVLT long delay free recall score, and APOE-e4 status.

Significant Variables	Wald Chi-square	df	p-value	Odds Ratio	95.0% C.I.
GDS score	5.02	1	< 0.03	1.28	1.03	1.58
Post-peak cortisol	5.41	1	0.02	1.83	1.10	3.05
CAR Slope	4.47	1	< 0.04	0.78	0.62	0.98

Model: Chi-square=29.22; df=6; p<.001

GDS = Geriatric Depression Scale

Post-peak cortisol = mean of 2 PM, 4 PM and bedtime samples (nmol/L)

CAR = Cortisol Awakening Response, Slope=30 minute after awakening - awakening (nmol/L)

CVLT = California Verbal Learning Test

APOE-e4 = Apolipoprotein E, e4 allele

C.I. = Confidence Intervals for Odds Ratio
