Ethnicity/Race	FVL Carriers	FVL Noncarriers	Relative Risk (95% CI)	P
African American (n = 1,381)	3/20 (15.0)	52/1,361 (3.8)	3.9 (1.3–9.9)	.04
Hispanic/Other (n = 1,256)	3/24 (12.5)	32/1,232 (2.6)	4.8 (1.6–12.8)	.03
White (n = 1,396)	2/77 (2.6)	37/1,319 (2.8)	0.9 (0.2–3.3)	1.00

FVL, factor V Leiden mutation; CI, confidence interval.
