The effect of vitamin supplementation on neurodevelopmental and clinical outcomes in very low birth weight and very preterm infants: A systematic review and meta-analysis

There are few and inconclusive data on the effect of vitamin supplementation in preterm infants on later neurodevelopment. Evidence for shorter-term outcomes is mostly of low certainty. Together with substantial heterogeneity in trial design, it therefore is difficult to recommend a specific supplementation regimen.
