ADHD = attention‐deficit/hyperactivity disorder; VADRS = Vanderbilt ADHD Diagnostic Rating Scales. Race/Ethnicity coded 1 = Black and/or Latinx, 0 = other. Medication statuses coded 1 = on medication at that timepoint, 0 = not on medication at that timepoint. Bolded rows represent significant coefficients. Coefficients for cohort and medication statuses were not interpreted to reduce risk of Type I Error.
