Values are means ± SEM; n = 8–10 pigs/group. Differences between treatment groups in plasma values were analyzed using ANOVA, Kruskal-Wallis, and Mann-Whitney U tests. Values in the same row with different superscripts differ P < .05. Groups are parenteral nutrition plus the following: Intralipid (IL), Intralipid plus vitamin E (ILE), Omegaven (OV), or Omegaven plus phytosterols (PS). ANOVA, analysis of variance; nd, not detected; SEM, standard error of the mean.
