Vitamin A to prevent bronchopulmonary dysplasia in very-low-birth-weight infants: has the dose been too low?

Abstract

A large clinical trial of vitamin A supplementation with 5000 IU/dose three times/week (25-114% more than the dose used in the three published clinical trials) is needed to assess whether vitamin A supplementation safely reduces the risk of bronchopulmonary dysplasia in very-low-birth-weight infants.
