Notes: The unadjusted difference in completion is 9.2 percentage points in outpatient and 15.4 percentage points in residential settings. Entries are bootstrap estimates of expression (1) applied to models in Table 2 and may differ slightly than direct application of expression (1) to results in Table 2 due to rounding of the OR reported

CI, confidence interval; OR, odds ratio.
