  1. aThe change from baseline to the other study time points corresponds to the mean change (95 % CI) for continuous outcomes and the ratio of the rate ratios (95 % CI) for count outcomes. P values were assessed on the basis of the treatment group*time interaction. For continuous outcomes, the time by treatment group interaction examined the change in the mean from baseline to a subsequent follow-up visit (12- and 24-months) for the adapted HF group compared to the usual care group and 95 % CI. For count outcomes (substance use problem severity, physical community integration, number of emergency department visits, number of arrests, days experiencing problems due to alcohol, days experiencing problems due to drugs), the treatment group*time interaction evaluated the ratio of rate ratios for each post-baseline visit (e.g. rate ratio at follow-up visit relative to baseline in the adapted HF group divided by the rate ratio at follow-up visit relative to baseline in the usual care group) and 95 % CI. In these analyses, baseline values were used as a reference time point for all comparisons at subsequent time points (12- and 24-months) and the usual care group was used as a reference group
