	FVL Carriers	FVL Noncarriers	Relative Risk (95% CI)	P
Preeclampsia	8/121 (6.6)	121/3,912 (3.1)	2.1 (1.0–4.1)	.06
Pregnancy loss	0/121 (0)	35/3,912 (0.9)	0	.63
Abruption	2/121 (1.7)	22/3,912 (0.6)	2.9 (0.3–10.7)	.16
SGA < 10th percentile^*	10/20 (8.3)	352/3,857 (9.1)	0.9 (0.5–1.6)	.77

FVL, factor V Leiden mutation; CI, confidence interval; SGA, birth weight small for gestational age.

Data are presented as n/N (%) or relative risk (95% confidence interval).

Based on live-born singletons.
