The association between the presence of placenta accreta and the odds ratios for adverse perinatal outcomes in twin vs. singleton pregnancies, as modelled by restricted cubic splines. Panel A. Caesarean section in twin pregnancies. Panel B. Caesarean section in singleton pregnancies. Panel C. Postpartum haemorrhage in twin pregnancies. Panel D. Postpartum haemorrhage in singleton pregnancies. The reference level for ORs is the median gestational week at delivery. The reference line is at Y = 1. These curves are adjusted for maternal age, PBMI, nulliparity, primigravida, the history of caesarean section, history of alcoholism, racquet placenta, velaria placenta, placenta previa, GDM, PE, ICP, FGR, ART. ART – assisted reproductive technology, GDM – gestational diabetes mellitus, FGR – foetal growth restriction, ICP – intrahepatic cholestasis of pregnancy, PBMI – pre-pregnancy body mass index, PE – preeclampsia.
