Values in bold indicates statistically significant.
*Nine patients used antenatal steroid with incomplete course in EP group, while 4 patients in MMP group.
†Forty-four patients required inotropes in EP groups, while only seven patients in MMP group.
EP, exceedingly preterm; MMP, more matured preterm; NEC, necrotizing enterocolitis.
