Theta beta ratio in attention deficit hyperactivity disorder using a multiverse analysis
Attention deficit hyperactivity disorder (ADHD) affects 5–7% of children worldwide, yet diagnosis continues to rely on clinical-behavioral assessments. The theta/beta ratio (TBR) derived from electroencephalography (EEG) has long been proposed as a complementary neurobiological marker of ADHD based on reports of elevated TBR in affected children. However, ac
