ADHD-RS inattention scores and ADHD-RS hyperactivity/impulsivity scores among the four groups at the baseline (month 0, V1) and the endpoint (month 12, V2).

ADHD-RS inattention scores and hyperactivity/impulsivity scores consistently decreased after 12 months among the four groups. Changes in ADHD-RS inattention scores (the Kruskal–Wallis test by ranks: 12.257, p = 0.007) were significantly different between the four groups during the 12 months.
