Change from baseline in Adult ADHD Investigator Symptom Rating Scale (AISRS) score at Week6

The Adult Investigator Symptom Rating Scale (AISRS) is an 18-item clinician rating scale to evaluate individual ADHD symptoms on a scale of 0 (none) to 3 (severe). The total sum ranges from 0 (no ADHD symptoms) to 54 (extremely severe ADHD symptoms). Negative change from Baseline indicates improvement. Mixed-effect model repeated measure (MMRM) was used for analysis.
