Role of Cerebroplacental Ratio in Predicting the Outcome of Pregnancies Complicated by Diabetes

Introduction: Our objective was to evaluate the strength of association and diagnostic performance of cerebroplacental ratio (CPR) in predicting the outcome of pregnancies complicated by pre- and gestational diabetes mellitus. Methods: PubMed, Embase, Cochrane, and Google Scholar databases were searched. Inclusion criteria were pregnancies complicated by gestational or pregestational diabetes undergoing ultrasound assessment of CPR. The primary outcome was a composite score of perinatal mortality and morbidity as defined by the original publication. The secondary outcomes included preterm birth gestational age (GA) at birth, mode of delivery, fetal growth restriction (FGR) or small for GA (SGA) newborn, neonatal birthweight, perinatal death (PND), Apgar score
