Values expressed as means ± standard deviations or counts (percentage of the group). CDH, congenital diaphragmatic hernia. LHR indicates lung-to-head ratio; O/E LHR, observed to expected lung-to-head ratio; ECMO, extracorporeal membrane oxygenation; p refers to the measure of the probability that an observed difference could have occurred just by random chance.
