Chi-square tests to assess rGE and rGG for the significant G × E and G × G synergistic effects discovered by the Cox proportional hazards model analysis

Significant Synergistic Effects	(1A-209) × (r.exercise)		(1A-209) × (3A-310)		(1A-209) × (3A-292)		(1A-209) × (3A-936)
	Regular exercise		3A-310		3A-292		3A-936
	Yes	No	Carrier	Noncarrier	Carrier	Noncarrier	Carrier	Noncarrier
% carrying 1A-209	40.87	39.83	39.59	40.54	39.44	40.71	40.73	39.35
P of chi-square test of rGE or rGG	.917		.937		.917		.913
Conclusion	rGE does not exist		rGG does not exist		rGG does not exist		rGG does not exist

Note: rGE = gene–environment correlations; rGG = gene–gene correlations.
