a
Odds ratio (RMC/control) based on the odds of being in given state vs. continuing to be in the community using at the end of the quarter.
b
Based on 896 observations on 275 unique people.
c
Based on 1020 observations on 314 unique people.
d
Days of treatment during the subsequent 90-day quarter; not considered for transition to treatment by the end of the quarter; as noted in the text, the effect of RMC on transition to recovery is mediated by its ability to increase treatment participation during the quarter.
