The predictive performance of the sFlt-1/PlGF ratio for MAOs could not be assessed, as only one participant experienced one or more MAOs (central serous chorioretinopathy, pulmonary edema, acute renal failure, and disseminated intravascular coagulation); the participant developed preeclampsia after 4 weeks and had a sFlt-1/PlGF ratio at baseline of 349.8. The gene discussed is PGF; the disease is central serous retinopathy.
