  1. Probability with 95% confidence interval.
  2. Remission using two definitions: *final score of ADHDRS-IV-PI ≤18, and **CGI-ADHD-S ≤2. ADHDRS-IV-PI = Attention-Deficit/Hyperactivity Disorder Rating Scale Parent Version: Investigator Administered and Scored; CGI-ADHD-S = Clinical Global Impression of ADHD Severity.
