Application of Shengxuening tablets for the prevention of anemia in pregnancy: stratified efficacy analysis based on serum ferritin levels and thalassemia subgroups

Puntos clave

• The research aims to evaluate the effectiveness of Shengxuening tablets in preventing anemia in pregnancy, particularly based on serum ferritin levels and thalassemia status.
• Analyzed SXN tablet efficacy across different maternal serum ferritin levels and thalassemia subgroups.
• Identified an optimal ferritin baseline for the greatest therapeutic response.
• Assessed the correlation between initial iron reserves and treatment outcomes.
• SXN tablets significantly reduced iron deficiency and anemia in pregnant women.
• Best outcomes were observed when treatment started at a base serum ferritin of ≥30 μg/L.
• Positive correlation found between serum ferritin levels and treatment response, underscoring the importance of adequate iron reserves.
