It is very uncertain whether parenteral nutrition with omega‐3 fish oil changes mortality compared with standard parenteral nutrition (very low certainty).
It is very uncertain whether postoperative enteral nutrition (Osmolite) via nasojejunal tube changes mortality compared with postoperative parenteral nutrition (PN) (very low certainty).
Standard parenteral nutrition may leads to lower mortality [within first 10 weeks after liver transplantation] compared with standard isotonic intravenous glucose solution (low certainty).
Parenteral nutrition plus branched‐chain‐amino‐acid‐enriched formula showed no clear difference in mortality [within first 10 weeks after liver transplantation] compared with standard isotonic intravenous glucose solution (low certainty).
