An Elevated Maternal Plasma Soluble fms-Like Tyrosine Kinase-1 to Placental Growth Factor Ratio at Midtrimester Is a Useful Predictor for Preeclampsia

Table 3

Comparison of sFlt-1, PlGF, and sFlt-1/PlGF ratio in term and preterm preeclampsia.

Variable	Term preeclampsia (𝑛=31)	Preterm preeclampsia (𝑛=44)	𝑃 value
sFlt-1 (pg/mL)	3960 (1268)	4910 (885)	0.01
PlGF (pg/mL)	101 (51)	95 (24)	0.12
sFlt-1/PlGF ratio	35.9 (14.2)	49.5 (12.8)	0.003

sFlt-1: soluble fms-like tyrosine kinase 1; PlGF: placental growth factor.
Data are presented as median (interquartile range).
𝑃 value < 0.05 is significant.
