Relatives had a lower mean number of lifetime AUD symptoms than did probands, but this was not statistically significant. There were no significant differences between relatives and probands on other covariates, with the exception of professional treatment, which was not calculated due to 100% prevalence in probands. Among relatives who received professional treatment or attended self-help meetings, 52.8% had their first treatment or attended their first meeting before the proband’s first treatment, 44.8% were treated after the proband’s first treatment, and 2.4% were treated during the same year.
