Regression of exercise induced switch trial gain (N = 131), b = unstandardized regression coefficient, SE = standard error, b^* = standardized regression coefficient.

	b	SE	b*	t	p
Intercept	−38.36	22.56		−1.70	0.091
DAT1/SLC6A3 rs46000	81.01	32.09	0.21	2.52	0.013
DRD2/ANKK1 rs1800497	66.94	31.68	0.18	2.11	0.037

rs46000 targeting the Dopamine transporter (DAT1) is coded 0 = C/C, 1 = C/A or A/A. rs1800497 targeting Dopamine D2 receptor density (DRD2)/ankyrin repeat and kinase domain containing 1 (ANKK1) is coded 0 = C/C, 1 = C/T or T/T. R² for the whole model is 0.08, the corresponding adjusted R² is 0.06.
