Slope (A and B) and offset (C and D) for the stimulant-treated attention-deficit/hyperactivity disorder (ADHD) group after medication washout (ADHD+; shaded bars, shaded lines) and the age- and sex-matched typically developing (TD; closed bars, solid lines) and medication-naive ADHD (ADHD−; open bars, dashed lines) subgroups. Error bars are ±SD. A: ADHD− has steeper slopes compared with both TD and ADHD+ when averaged across participants and electrodes. B: slopes were steeper in ADHD− for all electrodes tested. C: ADHD− has greater offset compared with TD and ADHD+ when averaged across participants and electrodes. D: this pattern holds when electrodes are considered individually. *P < 0.05, significant difference between TD and ADHD− after false discovery rate (FDR) correction. #P < 0.05, significant differences between ADHD− and ADHD+ after FDR correction.
