Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The objective of the study is to compare supplementation with vitamin D at 800 IU/day to usual care for the first 28 days after birth with respect to 25 (OH) vitamin D levels and indicators of likely or plausible effects of vitamin D supplementation on the function or structure of the lung, bones, immune system, and brain in extremely premature (EP) infants who are \<28 weeks gestational age (GA) or \<1000 grams of birth weight (BW). The study results will be analyzed as intention to treat Bayesian analyses (Frequentist analyses will also be performed).
