Descriptive and clinical information on research subjects.

	Controls (n = 6)	PTSD (n = 7)	p
Age	39.0 ± 7.5	44.4 ± 9.6	NS
Males	5 (83.3%)	7 (100%)	NS
Race			NS
Caucasian	5 (83.3%)	4 (57.1%)
African American	0 (0.0%)	3 (42.9%)
Hispanic	1 (16.7%)	0 (0.0%)
Combat exposure severity	9.67 ± 9.09	13.43 ± 5.71	NS
PTSD severity	11.7 ± 22.8	75.9 ± 13.3	<0.0005
HAM-D	4.0 ± 6.2	22.7 ± 10.6	<0.002

Combat exposure severity = CES total score; PTSD severity = CAPS total score. The p-values represent results of t-tests between groups except for the p-value for race, which is the result of Fisher’s exact test.
