(A–D) Subfoveal choroidal thickness correlations with angiogenic factors. A bivariate distribution of each of three serum factor levels and the sFlt-1:PlGF ratio with SFCT in the severe preeclampsia group is displayed with a red linear fit line. Correlation values are (A) r = 0.26, p = 0.738; (B) r = 0.36, p = 0.497 (C) r = 0.55, p = 0.002, and (D) r < 0.001, p = 0.973. NPP, normotensive postpartum; PlGF, placental growth factor; sEng, soluble endoglin; SFCT, subfoveal choroidal thickness; sFlt-1, soluble fms-like tyrosine kinase-1; sPE, severe preeclampsia.
