POST_HOC outcome

Timeframe: 6 months after randomization

Population: Data was extracted from VA medical records and there were many participants who did not have sufficient information in their chart

Clinical Global Index Scale (1 to 7) with 1 being full recovery and total abstinence. Scores 3 and below represent good recovery. Lower scores are better.
