Evidence Map

What The Sources Report

• However, a significant gap exists globally between folic acid supplementation practices and scientific evidence. [Li Jiahe (2026); evidence level 3]
• A study in China found that only 16.1% of pregnant women took folic acid at the correct time. [Li Jiahe (2026); evidence level 3]
• There is an elevated risk of severe maternal and perinatal complications faced by WWE, including eclampsia, placental abruption, embolism, cardiac disorders, complications arising from obstetric procedures and severe antepartum or postpartum haemorrhage, as well as foetal hypoxia, neural tube defects (NTDs), preterm delivery, low birth weight and major congenital malformations (MCMs). [Birbal Sumeshni (2026); evidence level 4]
• , 13 14, The high risk of foetal anomalies associated with AED use necessitates the routine application of prenatal ultrasound assessments to monitor foetal development.Systematic ultrasonographic evaluation allows for the early detection of structural malformations, including both MCMs and minor dysmorphic features. [Birbal Sumeshni (2026); evidence level 4]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation

For folic acid pregnancy guideline, the current source set is useful for orientation, but it is not yet broad enough for strong claims. Use cautious language and keep conclusions close to the cited sources.

Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
