The authors have done a commendable job following 3 cohorts (1991 to 1992, 1997, and 2005) of extremely preterm infants from 22 to 27 weeks' gestation to 8 years of age. Although the authors previously had shown that there was no improvement in moderate to severe disability at 8 years between 1991 to 1992 and 1997,2 their report3 of all 3 cohorts at 2 years of age identified a significant decrease in severe disability (15.4% to 3.7%) and severe developmental delay (14.8% to 3.7%) between 1997 and 2005 attributed to improvements in perinatal interventions.
