Differences in hematocrit-to-plasma albumin ratio as a predictor of severe maternal morbidity in hypertensive disorders of pregnancy: a retrospective cohort study

HCT-ALB is a practical and scalable biomarker for predicting SMM in HDP. Its integration into clinical protocols could improve risk stratification and early intervention. Future studies should validate these findings in multi-ethnic and multi-center populations, incorporating social and economic factors to enhance predictive models and global applicability.
