Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Predominantly Inattentive Presentation (ADHD-PI)
Patients selected via random sampling from patients either newly admitted to the clinic or already under follow-up for ADHD-PI, with no psychotropic medication use in the last 3 months. All participants were primary or secondary school students. ADHD subtype classification was determined based on Diagnostic and Statistical Manual of Mental Disorders-5 criteria following clinical interviews and scale assessments completed by both parents and teachers. Children with comorbid psychiatric or chronic medical conditions and those using psychostimulants were excluded.
No interventions assigned to this group
