Comparison of DD, PAPP-A, free β-hCG, and NT MoM among the four groups. (a) DD MoM; (b) PAPP-A MoM; (c) free β-hCG MoM; (d) NT MoM. DD: D-dimer; PAPP-A: pregnancy-associated plasma protein A; free β-hCG: free beta human chorionic gonadotropin; NT: nuchal translucency; GH: gestational hypertension; PE: preeclampsia; SPE: severe preeclampsia; MoM: multiple of median.
