PEN, partial enteral nutrition; TEN, total enteral nutrition; EAR, estimated average requirement.
Results are expressed as median (range). Values are based on the three day food diary completed at three and six weeks; those withdrawing from the study were included only if enteral nutrition continued for at least three weeks.
