PGF and preeclampsia: In another study, Ciciu et al. [36] found the sFlt-1/PlGF ratio to be reliable in terms of determining the diagnosis of pre-eclampsia and distinguishing established between pre-eclampsia and uncomplicated gestational hypertension: mean sFlt-1/PlGF values in cases already carrying a diagnosis of pre-eclampsia were 209.2 (with a standard deviation of 138.77) compared to recorded mean values of 46.08 (standard deviation 17.37) in the gestational hypertension group and just 3.9 in the control group (standard deviation 0.3).
