New evidence
Neural tube defect deaths in Nigeria dropped from 33% to 4.6% across recent decades — but the data comes from just 390 patients in a single-country review.
This is the first systematic review to track folate-linked mortality trends in a Nigerian pediatric population, so the drop is promising but rests on a small sample and may not apply to other regions or healthcare settings.
A systematic review of 390 Nigerian children with neural tube defects found that mortality rates fell sharply from 33.3% in the 1990s to 4.6% by the 2010s, coinciding with improved folate supplementation. However, the study is early evidence from a single clinical population, and the authors note that prevention gaps and care disparities persist.
Where this fits in the evidence
This is among the first studies we've indexed on Vitamin B9 for Reduced Neural Tube Defect Mortality — treat it as an early signal until more research accumulates.
