Ten-Year Follow-up of Children Born at <30 Weeks’ Gestational Age Supplemented With Thyroxine in the Neonatal Period in a Randomized, Controlled Trial

Abstract

Gestation-dependent effects of T4 supplementation remain stable over time. These effects do not prove beneficial effects of T4 in infants <28 weeks but should be the background for a new randomized, controlled trial with thyroid hormone in this age group.
