The impact of close surveillance on pregnancy outcome among women with a prior history of antepartum complications attributed to thrombosis: a cohort study

Table 2 Comparison of perinatal outcomes within the thrombophilic and non-thrombophilic groups before and after close surveillance.

	Thrombophilic group (N = 49)			Non-thrombophilic group (N = 48)

Preterm delivery	20 (41)	5 (10)	0.001	27 (56)	16 (33)	0.052
Complicated pregnancies	49 (100)	6 (12)	<0.001	48 (100)	19 (40)	<0.001

Placental abruption	18 (37)	1 (2)	<0.001	18 (38)	5 (10)	0.004

* McNemar test
Complicated pregnancies = the reappearance of one or more of the thrombophilic complications considered (fetal death, SGA, severe pre-eclampsia and placental abruption)
SGA = neonate small for gestational age
IUFD = intrauterine fetal death
