Conditional indirect effect.

	Conditional Indirect Effect by Combined DRD2 Allele Type
	Estimate	SE	Bootstrap Lower 95% CI	Bootstrap Upper 95% CI
Combined DRD2 nonrisk allele carriers	0.66	0.79	−0.58	2.68
Combined DRD2 risk allele carriers	52.45 *	22.73	14.21	104.91

Note: Combined DRD2 risk allele carriers refer to individuals carrying both the T allele of DRD2 C957T and the A1 allele of DRD2 Taq1. Combined DRD2 nonrisk allele carriers are those carrying only one or neither of the T allele of DRD2 C957T and the A1 allele of DRD2 Taq1; * p < 0.05.
