Scatter plots (with regression lines) showing associations between DNA methylation and functional measures (boys with FBB-ADHS total scores ≤0.5, controls: black circles; boys with FBB-ADHS total scores >0.5 and ≤1, ADHD-low: red circles; boys with FBB-ADHS total scores >1, ADHD-high: green circles). 5 of the 6 CpGs were hypermethylated in the groups with higher ADHD scores. It has to be noted that residuals are depicted which are centered at 0. dRTVar = difference of reaction time variability between blocks with and without motivational incentives.
