Day of life when full enteral feeds were attained median (IQR) 8 (6-10) 8 (6-10) p = 0.68
Cumulative energy intake (*) [kcal/kg] first four weeks of life median (IQR) 3431 (3219-3601) 3438 (3356-3562) p = 0.58
Cumulative protein intake (**) [g/kg] first four weeks of life median (IQR) 105 (101-110) 109 (105-116) p = 0.002
SDS-difference for weight (SDSd28 – SDSbirth) median (IQR) -0.64 (-1.08-0.34) -0.41 (-0.7-0.17) p = 0.017

Age at discharge [days] median (IQR) 72 (48-98) 69 (44-93) p = 0.41

IQR = interquartile range.

(*) = assuming human milk energy content of 67 kcal/100 ml.

(**) = assuming human milk protein content of 1.4 g/100 ml.
