Timing matters: Unveiling the distinct effects of early vs late onset pre-eclampsia on mothers and newborns in a tertiary hospital in Bangladesh

Objective: Pre-eclampsia (PE) is a significant cause of maternal and perinatal morbidity and mortality worldwide. The clinical course and severity of PE can vary depending on the gestational age at onset. However, limited data from developing countries including Bangladesh stratify outcomes by onset timing, hindering context-specific management. This study aimed to differentiate maternal and perinatal outcomes associated with early-onset PE (EO-PE, <34 weeks) versus late-onset PE (LO-PE, ≥34 weeks) in a tertiary care setting in Bangladesh.
