Demographic and drinking data for subjects with usable scan data.

	Lower AW		Higher AW		Test for difference
	Placebos	GBP/FMZ	Placebos	GBP/FMZ	Test for difference
N	14	22	6	6
Age	47.9 (11.2)	44.0 (12.2)	53.0 (6.4)	48.0 (4.8)	n.s.
Gender (% female)	21.4	22.7	33.3	16.7	n.s.
Education (years)	15.0 (2.8)	14.1 (2.2)	15.3 (2.1)	13.0 (2.4)	n.s.
ADS	12.4 (6.0)	13.4 (5.2)	13.0 (3.5)	18.5 (7.1)	n.s.
OCDS (baseline)	13.9 (4.8)	15.0 (4.1)	21.2 (4.9)	19.3 (6.0)	Higher AW > Lower, p = .001
Heavy drinking days, %
Baseline (past 90 days)	91.7 (9.6)	86.8 (14.8)	90.4 (18.9)	92.4 (17.0)	n.s.
Pre-scan	5.4 (6.4)	13.3 (16.5)	2.2 (3.5)	1.2 (2.9)	Lower AW > Higher, p = .001
Post-scan^*	10.6 (19.7)	23.1 (25.5)	8.4 (13.0)	4.6 (9.7)	Lower AW > Higher, p = .04

All figures except Ns are means (standard deviations). Pre- and post-scan drinking data represent the percentage of heavy drinking days for each subject before vs. after that subject’s scan. ADS, Alcohol Dependence Scale; OCDS, Obsessive Compulsive Drinking Scale; n.s., not significant.

Excludes participants who dropped out after the scan (N = 5; 1 from low AW/placebo group, 3 from low AW/GBP/FMZ group, and 1 from higher AW/GBP/FMZ group).
