Intervention Effects on Categorical Alcohol-Related Outcomes

	Control (n = 24)	Intervention (n = 24)
	N (%)	N (%)	OR (95% CI)	ORa (95% CI)	p
90-day period prevalence abstinence	14/19 (73.7%)	18/20 (90.0%)	3.2 (0.5-19.1)	3.4 (0.5-21.0)	.19
Healthy pregnancy	14/23 (60.9%)	19/23 (82.6%)	3.1 (0.8-12.0)	3.3 (0.8-13.8)	.09
Treatment-seeking	0/19	1/20 (5.0%)	---	---	---

Note. The intervention was a 20-minute, brief intervention delivered via a Tablet and completed following a prenatal care appointment, plus three subsequent tailored mailings. Period prevalence abstinence over the past 90 days was measured at delivery. Healthy pregnancy was defined as a live birth of ≥ 2500 grams with no admission to Neonatal Intensive Care Unit. ORa values are adjusted for baseline alcohol use, and treatment-seeking was defined as any services of any kind for alcohol use, including 12-step groups. All p values are for adjusted OR (ORa).
