Clinical trial design in neonatal pharmacology: effect of cent...

Survival for premature neonates has improved dramatically over the past 20 years; however, there has been minimal improvement in prematurity-associated morbidities. Morbidity rates and assessment of outcomes vary across neonatology intensive care units (NICUs). Here, we address the reasons underlying these differences, note the impact that this center variation has on trial design and interpretation, and highlight the success of the efforts in pediatric oncology to develop standards of care through the conduct of multicenter clinical trials.
