Uni- and multivariate analyses adjusted by Framingham risk factors including age, sex, hypertension, diabetes mellitus, current smoking, and dyslipidaemia

	Univariate			Multivariate (CAD RF adjusted)
	HR	95% CI	P-value	HR	95% CI	P-value
Normal coronary artery
Right dominant (vs. left dominant)	0.46	0.16–1.32	0.1496	NS	NS	NS
Non-obstructive CAD
Right dominant (vs. left dominant)	0.95	0.41–2.21	0.8962	NS	NS	NS
Obstructive CAD
Right dominant (vs. left dominant)	1.04	0.68–1.59	0.8461	NS	NS	NS

HRs of RCD vs. LCD for the composite outcome of all-cause mortality, non-fatal MI, and coronary revascularization according to the extend of CAD (non-obstructive: <50% stenosis, obstructive: >50% stenosis) on CCTA. Patients with a balanced coronary artery system were excluded from the analysis.

CAD, coronary artery disease; RF, risk factor; HR, hazard ratio; CI, confidence interval.
