Characteristics of the severe PE and control groups.

Characteristics	Control (n=37)	Severe PE (n=43)
Age, years	27±3a	28±4
Gestation length, weeks (range)	33±4b (25–38)	33±3 (25–37)
Systolic MAP, mmHg	115±10	159±18
Diastolic MAP, mmHg	71±9	99±13
Proteinuria, g/24 h	Negative	5±1
Placenta weight, g	692±135c	623±125
Infant birth weight, g	3,245±525d	1,917±532

Age, gestation length and blood pressure are expressed as the mean ± SD. No significant difference was identified between the severe PE and control groups:

^aP=−0.274 and

^bP=0.983, respectively. Placenta weight and infant weight were significantly lower in the severe PE group:

^cP=0.023 and

^dP=0.005, respectively.

PE, preeclampsia; MAP, mean arterial pressure.
