| Continuous variables are expressed as mean (standard deviation). Categorical variables are presented as number (proportions). One unit of packed RBC contained 200 mL. RBC – red blood cells; FFP fresh frozen plasma; DIC – disseminated intravascular coagulation; UAE – uterine artery embolization; AABO – abdominal aorta balloon occlusion; PAS – placenta accreta spectrum disorder; NICU – Neonatal Intensive Care Unit. Statistical analysis was performed using SPSS 26.0 software (IBM Corp, Armonk, NY, USA). | |||
