Test 1 — The measure showing the largest MTC treatment effect was treated as an outlier and removed in every domain with 2 or more measures (i.e., substance use, mental health, crime).

Test 2 — A measure with limited treatment effect (i.e., half the strength of the average of the observed measures) was added to each study in every domain.

Test 3 — A hypothetical study with no treatment effects was added. This study had the average number of subjects (92 MTC & 51 comparison=143), and the same number of measures for each domain. An odds ratio of 1.00 and the mean standard error from all other studies were assigned to the hypothetical study.

Test 4 — All HIV cases were included.

An odds ratio less than one indicates a greater improvement for clients in the MTC group than in the comparison group.

Sensitivity tests were not conducted on the HIV-risk behavior domain since results for original findings were not significant.
