Data are presented as Mean±SD, mean (median, interquartile) or number of cases with percentages [n(%)]. #Severe respiratory complication is defined as any of the following conditions within 72 h after birth: CPAP or HFNC for at least 12 hours; supplemental oxygen with a fraction of inspired oxygen of 0.3 or more for at least 4 continuous hours; mechanical ventilation; and death. ##Analysis was limited to ICU admission cases. ###Two umbilical venous samples were lost for analysis of ABG in each group.
