Table 3. Regressions of slopes on different-disorder intercepts and regressions of treatment on slopes.

Treatment Interval	β	SE
1. Slope 1 regressed on ADHD	-0.16	0.09
2. Slope 2 regressed on ADHD	-0.21	0.14
3. Slope 3 regressed on SUD	0.10	0.08
4. Slope 4 regressed on SUD	0.13	0.09
5. Treatment on Slope 1	-0.03	0.07
6. Treatment on Slope 2	-0.07	0.11
7. Treatment on Slope 3	0.01	0.07
8. Treatment on Slope 4	0.06	0.08

Note. β = standardized regression coefficient, SE = standard error.

p < .05.

Slope 1 = SUD slope from Week 0 –Week 4; Slope 2 = SUD slope from Week 4 – Week 16; Slope 3 = ADHD slope from Week 0 – Week 4; Slope 4 = ADHD slope from Week 4 – Week 16.
