Table A.1.

Cost-Effectiveness Analysis Results with Licensing Fee ($2016)

		Any Treatment Initiation 6MFU

Treatment	Mean Cost (C)	Mean Effectiveness (E)	ICER (ΔC/ΔE)
SAU	$—	25% (0.04)	—
MI	134.27 ($0.10)	29% (0.05)	Dominated by extension
MAPIT	$139.37 ($0.12)	37.2% (0.05)	$11.42

Note: Treatments are ranked in ascending order according to cost. 6MFU—6-Month Follow-Up, ICER—Incremental Cost Effectiveness Ratio, MAPIT—Motivational Assessment Program to Initiate Treatment, MI—Motivational Interviewing, SAU—services as usual. The Δ compares one row of the table with the previous row, adjusting for covariates. In the current study, dominated by extension means the ICER decreases in value across increasingly expensive interventions.
