Predictive value of the sFlt-1/PlGF ratio for preeclampsia in twin pregnancies: a retrospective study.

: This study aimed to investigate the efficiency of the soluble Fms-like tyrosine kinase 1 (sFlt-1)/placental growth factor (PlGF) ratio in predicting preeclampsia (PE) within 4 weeks in twin pregnancies.: Seventy-eight women with serum angiogenic markers measured at 28 + 0 to 30 + 6 weeks of gestation were enrolled. A receiver-operating characteristic curve was used to determine the sFlt-1/PlGF ratio threshold to predict PE.: A cutoff value for the sFlt-1/PlGF ratio of 22.2 predicted PE presence within 4 weeks.: An sFlt-1/PlGF ratio of ≤22.2 is potentially indicative of PE absence within 4 weeks in twin pregnancies.
