Outcome
Neonatal outcomes that were measured in the analysis were Apgar scores at 1 and 5 min on the day of delivery.

Apgar scores from 1 to 7 (coded 0) and above 8–10 (coded 1) for Apgar scores at 1 min, and Apgar scores from 1 to 7 (coded 0) and 8–10 (coded 1) for Apgar scores at 5 min. This categorization of apgar scores was adapted by the consensus of the American Academy of Pediatrics on measurement of apgar scores and their usefulness [
