Basic characteristics of all enrolled neonates.

Data are expressed as mean (standard deviation) or numbers (%). NLD neonates were intubated for delivery room resuscitation and kept ventilated to reduce their metabolic demand during hypothermia, according to our routine clinical protocol. All patients were discharged home with no respiratory support and with normal neurological exam and brain magnetic resonance imaging.

数据以均值（mean）±标准差（standard deviation）或例数（百分比）形式呈现。NLD新生儿遵循本院常规临床诊疗规程，在产房复苏过程中接受气管插管，并在低体温（hypothermia）期间维持机械通气以降低其代谢需求。所有患者均顺利出院，出院时无需呼吸支持，且神经系统检查及脑部磁共振成像（brain magnetic resonance imaging）结果均正常。
