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

Table 5

Optimum cutoff values and odds ratio for preeclampsia according to cutoff values.

Variable	Optimum cutoff value	Odds Ratio	95% Confidence Interval
sFlt-1 (pg/mL)	3198	37.2	17.7–78.1
PlGF (pg/mL)	138	20	10.2–39.5
sFlt-1/PlGF ratio	24.5	67	29.3–162.1

sFlt-1: soluble fms-like tyrosine kinase 1; PlGF: placental growth factor.
