Notes: Standard error of estimate in parentheses. All costs are in 2009 U.S. dollars. An economically dominated intervention either is more expensive and less effective than another or has a higher calculated incremental cost-effectiveness ratio (ICER) than the next most expensive. Economically dominated interventions were removed from consideration in the analysis. AO = assessment only; MI = motivational interviewing; FB = feedback only; MIFB = motivational interviewing with feedback.
