Participant flow diagram of very low birth weight infants enrolled in the Optimizing Mothers’ Milk for Preterm Infants Fortifier trial. Infants were randomized to receive a human milk-based fortifier or a bovine milk-based fortifier added to an entirely human milk diet (maternal or donor) during initial hospitalization. Participants returned for neurodevelopmental testing with the Bayley Scales of Infant and Toddler Development, Third Edition at 18-mo corrected age per routine clinical follow-up.
