Parent and teacher ratings of children’s ADHD severity and impairment were collected, and neuropsychological assessments of children were conducted at BL-F3. The Mean (SD) interval in months between BL and F1, F1 and F2, and F2 and F3 was 11.99 (1.21); 11.65 (1.69); 11.80 (1.51) months. This study was approved by the Institutional Review Board (IRB). Following a full description of the study, all parents signed IRB-approved informed-consent forms.
