LaGamma 1985	This was not a randomised controlled trial
Said 2008	Infants in the delayed progressive enteral feeding group received minimal enteral nutrition prior to feed advancement as a co‐intervention
Sanghvi 2013	Both groups received early enteral feeds
Weiler 2006	Infants in both groups received some enteral feeds before 4 days after birth
