OQ-45 at the beginning of the treatment Symptoms of clinical significance n (% yes)	n = 55 32 (58.2%)	Yes No	11 (34.4%) 8 (34.8%)	0.98 (0.32–3.03)	0.98
OQ-45 at the end of treatment Symptoms of clinical significance n (% yes)	n = 49 22 (44.9%)	Yes No	6 (27.3%) 8 (29.6%)	0.89 (0.26–3.11)	0.86

The proportion of the women who achieved abstinence is presented for each variable.

p-values and odds ratios (OR) are based on continuous variables for age (calculating the OR per five years), years of education and for the OQ-45.2.

All other variables were dichotomized in the analyses. OR is the ratio for an increase of one unit in each of the predictors.

	Total sample n = 57	Subgroups	Number and percentage of abstinence	OR (95%CI)	p-value
Onset age of AUD (years) Mean (SD) OR per five years	43.5 (13.3)	0–24 25–44 ≥ 45	1 (16.7%) 11 (45.8%) 7 (25.9%)	1.00 (0.82–1.24)	0.96
Years of AUD Mean (SD)	7.5 (7.8)	0–5 >5	14 (50.0%) 5 (17.2%)	0.91 (0.82–1.00)	0.053
Dependence criteria according to the DSM-IV at the start of treatment	3 (5.3%) 10 (17.5%) 44 (77.2%)	1–2 criteria 3–4 criteria 5–7 criteria	1 (33.3%) 2 (20.0%) 16 (36.4%)	1.12 (0.76–1.67)	0.56
Months of treatment Mean (SD)	11.0 (8.2)	0–10 >10	10 (29.4%) 9 (39.1%)	1.02 (0.95–1.09)	0.63
Grams of alcohol/week at treatment start Mean (SD)	315.5 (307.0)	≤ 108 >108	2 (15.4%) 17 (38.6%)	3.46 (0.68–17.57)	0.13
Grams of alcohol/week at the end of treatment Mean (SD)	n = 51 116.7 (259.2)	≤ 108 >108	12 (30.8%) 3 (25.0%)	0.75 (0.17–3.27)	0.70
Drinking goal of abstinence at the start of treatment n (yes%)	22 (38.6%)	Abstinence Low-risk drinking	10 (45.5%) 9 (25.7%)	2.41 (0.78–7.46)	0.13
Drinking goal of abstinence at the end of treatment n (yes%)	n = 52 21 (40.4%)	Abstinence Low-risk drinking	13 (61.9%) 3 (9.7%)	15.17 (3.45–66.69)	< 0.001
Change alcohol habits, large change at the end of treatment n (yes%)	n = 52 35 (67.3%)	No or some change Large change	3 (17.6%) 13 (37.1%)	2.76 (0.67–11.44)	0.16

The percentage of abstinence reflects the proportion of participants who achieved abstinence within each subgroup. p-values and odds ratios (OR) are based on dichotomous variables for drinking goal, and the change of alcohol habits. All other variables were used as continuous variables in the analyses. OR is the ratio for an increase of the predictor in one unit.
