Notes.
Nutrition components, volumes and calories of ELBW infants in their first week of life were analyzed prior and after introduction of aggressive feedings. Data are presented as median and interquartile ranges. After inspection of histograms for normal distribution, total days on PN were tested using the Mann Whitney U test, all other parameters using the student’s t test.
P values < 0.05 were considered statistically significant and printed in bold letters.
