The potential effects of an extended alcohol withdrawal treatment programme on morbidity and mortality among inpatients in the German city of Bremen: a simulation study

Table 1 Data required for simulating AUD treatment outcomes

Study	Sample size at baseline (lost to follow-up)^a	Outcome		Mean outcome in QWT vs SWT group	Dispersion parameters for negative binomial distribution
Driessen et al., 1999 [25]	n in SWT = 79 (42)	A)	Number of hospitalisations within 5 years	3.5 (4.4)^b vs. 7.3 (11.3)^b	QWT: 0.774
	n in SWT = 79 (42)				SWT: 0.443
	n in QWT = 101 (44)				SWT: 0.443
		B)	Length of hospitalisations within 5 years	55.7 (75.4)^b vs. 135.8 (167.3)^b	QWT: 0.551
		B)	Length of hospitalisations within 5 years	55.7 (75.4)^b vs. 135.8 (167.3)^b	SWT: 0.662
Bauer et al., 2000 [23]	n in SWT = 90 (40)	C)	Proportion abstinent within 28 months	31.5% (29/92)^b vs. 14.4% (13/90)^b	N/A
	n in QWT = 92 (35)	C)	Proportion abstinent within 28 months	31.5% (29/92)^b vs. 14.4% (13/90)^b	N/A
	n in QWT = 92 (35)	D)	Proportion dead within 28 months	7.6% (7/92)^b vs. 14.4% (13/92)^b	N/A

Note. AUD Alcohol use disorder, QWT Qualified withdrawal treatment, SWT Somatic withdrawal treatment; N/A Not applicable
^a Patients lost to follow-up (i.e., could not be contacted) were not included in calculation of the means and standard deviation for indicator A) and B) and were regarded as non-abstinent and not dead for outcomes C) and D), respectively
^b Numbers in brackets indicate standard deviation (continuous variables) or the numerator and denominator (binary variables)
