The actual outcome rate is calculated as the number of resuscitated infants at a given gestational age with the specified outcome as a proportion of all resuscitated infants born at that gestational age. The projected outcome rate and 95% confidence interval were estimated using models assuming that all hospitals achieved the average antenatal corticosteroid coverage rate for resuscitated infants observed at 25 and 26 weeks (89.2%).

Of the 24 hospitals, 20 contributed to the models. At 4 hospitals, no infants were resuscitated.
