Proteinuria is associated with worse outcomes in babies born to mothers with preeclampsia: A retrospective cohort study at a tertiary referral hospital in Brazil.

To evaluate whether the presence of proteinuria, although no longer mandatory in the revised diagnostic criteria, results in worse maternal and fetal outcomes in preeclampsia (PE). A retrospective cohort study was conducted, analyzing data from pregnant patients diagnosed with PE between January 2015 and December 2019 at a tertiary care center in Brazil. Ethical approval was obtained, and the patient records were reviewed to assess maternal and perinatal outcomes based on the revised diagnostic criteria by the College of Obstetricians and Gynecologists, focusing on the presence or absence of proteinuria.
