Variable	No Behavioral Consultation	Yes Behavioral Consultation	Effect Size	Stat. Sig.
Taking Medication at School	81% [64, 91]	63% [45, 78]	OR = 0.44 RR = 0.88
Taking Medication at Home	63% [45, 78]	26% [17, 38]	OR = 0.21 RR = 0.50	**
For Those Medicated at School, Mean School Dose IR MPH (mg/kg/dose b.i.d.)	0.41 [0.33, 0.48]	0.32 [0.26, 0.37]	-	†
For Those Medicated in Evening, Mean Evening Dose IR MPH (mg/kg/dose q.d.)	0.31 [0.23, 0.39]	0.28 [0.21, 0.35]	-
For Those Medicated on Weekend, Mean Weekend Dose IR MPH (mg/kg/dose b.i.d.)	0.37 [0.26, 0.47]	0.30 [0.21, 0.40]	-
Total Methylphenidate Intake Over Full Year (mg)	4263 [3228, 5299]	2443 [1762, 3124]	-	**
Teacher Iowa Conners Sum Score Inattention/Overactivity	5.5 [4.2, 6.8]	6.9 [6.0, 7.9]	d = −0.41
Teacher Iowa Conners Sum Score Oppositional/Defiant	3.5 [1.9, 5.0]	3.7 [2.6, 4.7]	d = −0.04
Parent Iowa Conners Sum Score Inattention/Overactivity	8.3 [7.3, 9.3]	7.4 [6.7, 8.1]	d = +0.34
Parent Iowa Conners Sum Score Oppositional/Defiant	7.0 [5.6, 8.5]	5.7 [4.7, 6.7]	d = +0.32

Note. OR = odds ratio, RR = relative risk, IR = instant release formulations, MPH = methylphenidate. Values in second and third columns are pooled, least-square means, adjusting for previous use of medication at school and home, with numbers in brackets indicating 95% confidence intervals about these means. d is Cohen’s D, calculated here as the difference between the least squares means over the sample-wide pooled standard deviation (positive sign indicates an advantage of Yes Behavioral Consultation). The “Stat. Sig.” column indicates statistical significance of the comparison of those assigned to behavioral consultation vs. no behavioral consultation.
