Conclusion
Taken together, we developed for the first a Cox proportional-hazards model based on baseline levels of vitamin B5, B6, and B9 to predict miscarriage risk in pregnant women with a history of SA. On one hand, the model may facilitate the identification of pregnant women at high risk for RSA, thereby timely implementing individualized treatment and intervention
Very nice study - up to the last sentence which advises not to overdose!?
