Primary Outcomes	SC (n = 89)	SC+CM (n = 210)	SC (n = 14)	SC+CM (n = 42)
LDA(wks)^a	2.8 (0.4)	5.0 (0.3)	1.7 (1.0)	4.5 (0.6)
Percent Negative Samples^b	65.9 (2.3)	67.9 (1.6)	74.2 (5.5)	76.4 (3.3)
Treatment Retention (wks) ^a	5.7 (0.4)	7.5 (0.3)	5.3 (1.0)	7.5 (0.6)

Notes. Values are means and standard errors, controlling for study, age, gender, baseline toxicology result, and baseline ASI employment and psychiatric scores.
