Danish national study in infants with extremely low gestational age and birthweight (ETFOL)
ETFOL aimed to examine neonatal care and health outcomes, focusing on ventilatory support and chronic lung disease (CLD) in a population-based study. A total of 477 infants were involved in the cohort, with 386 having a gestational age (GA) of <28 weeks, and 385 having a birthweight of <1000g, and were recruited via the National Danish Birth Register. Baseline assessments were conducted as perinatal assessments, with follow-ups occurring at 5 months, 1, 2, and 5 years old, the final one in the year 2000, with no planned follow-ups for the future.
