Identifies optimal haemoglobin ranges for maternal and neonatal outcomes, suggesting clinical implications.
The findings of this study reveal U-shaped relationships between maternal Hb concentrations and maternal/neonatal outcomes, with 10.5-12.5 g/dL as the optimal Hb concentration during the second and third trimesters, considering combined risks and clinical feasibility. Future multicentre studies are warranted to validate these ranges in broader populations.
