Data sample characteristics

	Age (SD), year			Ethanol Intake (SE), g/kg/d
MRI	CTR	NHD	HD	CTR	NHD	HD
1	4.7 (0.6)	5.1 (0.6)	4.8 (0.8)	0.0	0.0	0.0
2	5.8 (0.6)	6.2 (0.6)	5.9 (0.7)	0.0	1.8 (0.5)	3.3 (0.8)
3	6.3 (0.6)	6.6 (0.6)	6.4 (0.7)	0.0	2.1 (0.4)	3.6 (0.8)

One-way ANOVA revealed no significant difference in age at the beginning of the study (MRI 1) among three groups of subjects (F_(2,60) = 1.3, p = 0.28). Repeated-measures ANOVA revealed significant effects of MRI (2 vs 3: F_(1,43) = 11.3, p < 0.01) and group (NHD vs HD: F_(1,43) = 67.9, p < 0.0001) on ethanol intake with no significant interaction (F_(1,43) = 0.06, p = 0.8).
