Clinical Endpoint Event Rates Among Racial and Ethnic Minorities by Treatment

	Events, N (%)		Kaplan-Meier 4-Year Event Rate, %
	Ablation (n = 62)	Drug (n = 65)	Ablation (n = 62)	Drug (n = 65)	Adjusted Hazard Ratio^* (95% CI) (Ablation : Drug)
Primary Endpoint (all-cause mortality, disabling stroke, serious bleeding, or cardiac arrest)	8 (12.9)	15 (23.1)	12.3	27.4	0.32 (0.13, 0.78)
All-cause mortality	6 (9.7)	12 (18.5)	8.1	20.2	0.28 (0.10, 0.79)
Disabling stroke	0 (0.0)	2 (3.1)
Serious bleeding	1 (1.6)	4 (6.2)
Cardiac arrest	1 (1.6)	3 (4.6)
Secondary Endpoint: Death or cardiovascular hospitalization	37 (59.7)	45 (69.2)	59.4	70.7	0.73 (0.47, 1.13)

Hazard ratio and associated CI=confidence interval were calculated using an adjusted Cox model.
