	All patients	Non-AD			AD
	N = 792	male	female	total	male	female	total
	N = 792	N = 317	N = 403	N = 720	N = 52	N = 20	N = 72
Number of days of reduced work in past 30 days due to any health condition (WHODAS 2.0 H3), mean (SD)	3.0 (6.1)	2.3 (5.1)	3.3 (6.2)	2.9 (5.8)	4.0 (8.2) *⁺	3.6 (7.5)	3.9 (8.0) *⁺

Note
Significance between patients with and without AD was tested with zero-inflated negative binomial regressions for all count variables, using alcohol dependence and age as predictor in both count (predicting values >0) and logit (predicting 0) model. The following symbols indicate a significant AD predictor: count model * p < .05 ** p < .01 *** p < .001; logit model ° p < .05 °° p < .01 + or – behind the symbol indicates valence of respective coefficient
For the binary variable indicating at least one day with impaired productivity due to drinking, an age-adjusted logistic regression was conducted. The same legend for p-values also applies to negative binomial models
