Time-to-event curve showing the need for a transfusion during the first 28 days of life among preterm infants with congenital heart disease receiving delayed cord clamping (DCC) or early cord clamping (ECC) at birth. Log-rank (Mantel-Cox) comparison demonstrates significant differences in the curves (P=0.02). The corresponding Mantel-Haenszel hazard ratio (HR) for transfusion need in the ECC group versus the DCC group is 3.1 with a 95% confidence interval of 1.2 – 7.9.
