Ex-Gaussian parameters in subjects presenting “risk” versus subjects presenting “non-risk” alleles for DRD4 and SCL6A3/DAT1 genes.

Gene	Parameter (ms)	Risk group	Non-risk group	Unadjusted p-valuea	Adjusted p-valueb
DRD4	μ	212.2	209.1	0.96	0.56
	σ	52.3	47.3	0.24	0.94
	τ	122.7	83.2	0.013*	0.14
SCL6A3/DAT1	μ	214.8	201.8	0.48
	σ	51.2	47.2	0.92
	τ	97.3	117.2	0.26

*Indicates a significance level of 0.05 or less.

^aUnadjusted p-value was obtained by means of Wilcoxon sum rank test.

^bPresented p-values are adjusted by age, sex, and clinical status (ADHD, healthy sibs, and/or TD children).
