However, from birth through to 34 weeks PMA, there was a mean change in IGF-I of 2.8 ± 2.2 μg/L per week in infants with BPD compared to 4.5 ± 1.8 μg/L per week in infants without BPD (OR 0.68 (95% CI 0.48–0.96, p = 0.026; corrected for gestational age)). The gene discussed is IGF1; the disease is bronchopulmonary dysplasia.
