^*Dextrose was increased to 31.45 g (to provide 105.68 kcal) in the PN solution to which no lipids were added (NoL-PN) to make the solution isocaloric to PN with lipids.

^†Lipid source was Intralipid (20% emulsion) in SO-based PN (SO-PN) or Omegaven (10% emulsion) in FO-based PN (FO-PN). The composition of the lipid emulsions is detailed in Table 2.

^‡MTE-5 contains zinc, copper, manganese, chromium, and selenium.
