PGF and preeclampsia: Furthermore, significantly higher sFlt-1/PlGF values could be noticed in case of patients who developed pre-eclampsia at any time during pregnancy compared to the control (45.5 vs. 6.6), among patients who developed fetal adverse outcomes compared to the control within 1 and 4 weeks (148.9 vs. 7.4 and 86.9 vs. 6.3, respectively), and in women with pre-term delivery (<37 weeks) compared to term delivery among both early-onset and late-onset preeclampsia.
