  • The results were based on the final multiple logistic regression model derived controlled for GA, gender, Apgar score at 5 min, outborn status, prenatal steroid, vertex presentation, cesarean delivery, multiple births, maternal hypertension, and maternal diabetes. Values presented are AOR (95% CI).
