| Measure | Time frame | Description |
|---|---|---|
| Safety-incidence of treatment emergent adverse events | 6 months | incidence of treatment emergent adverse events |
| Attention Deficit Hyperactivity Rating Scale - IV (ADHD RS-IV) Preschool-Home Version | 6 weeks | Change from Baseline to end of double-blind treatment in the total score of the Attention Deficit Hyperactivity Rating Scale - IV (ADHD RS-IV) Preschool-Home Version |

| Measure | Time frame | Description |
|---|---|---|
| Intellectual Performance of Children Using Child Behavior Checklist 4-18 Years (CBCL 4-18) | Weeks 1-6 | CBCL was standardized for children ages 4 to 18 years and measured child internalizing and externalizing behaviors and total problems. The 4-18 years' checklist contains 140 questions and responses were recorded on a Likert scale: 0 = Not True, 1 = Somewhat or Sometimes True, 2 = Very True or Often True. The range of possible values was 0-280 (0=good to 280=worst). |
| incidence of adverse events | 6 weeks | incidence of adverse events |
| Mean Clinical Global Impression - Severity (CGI-S) score | Weeks 1-6 | CGI-S: 7-point clinician rated scale to assess severity of participant's current illness state; range: 1 (normal - not ill at all) to 7 (among the most extremely ill patients). Higher score = more affected |
| Children's Global Assessment Scale (CGAS) | Week 6 | CGAS: clinician-rated global assessment item for children based on symptoms and social functioning in home, school, and community settings. Scores on this single item range from 1 (most impaired) to 100 (healthiest); higher levels indicate greater health, with descriptive anchors for every 10-point interval. Scores above 70 on this scale are considered within the normal range; lower score indicates need for increased supervision. |
| Clinical Global Impression of Improvement (CGI-I) Scale Score | weeks 1-6 | CGI-I: 7-point clinician rated scale ranging from 1 (very much improved) to 7 (very much worse). Clinician responded to a question: Compared to your subject's condition at the beginning of treatment, how much has your subject changed?. Improvement was compared to baseline and was defined as a score of 1 (very much improved), 2 (much improved), or 3 (minimally improved) on the scale. Higher score = more affected. |
