Table 1 Characteristic of study subjects by parity and gestational age

From: Difference of concentration of placental soluble fms-like tyrosine kinase-1(sFlt-1), placental growth factor (PlGF), and sFlt-1/PlGF ratio in severe preeclampsia and normal pregnancy

Characteristics Group p value
Preeclampsia (n = 18) Normal (n = 19)
