Notes.
Body weight and feed intake of rats fed control (C, n = 6), high fat diet (HFD, n = 9), fish oil-high fat diet (FO-HFD, n = 9) or krill-oil high fat diet (KO-HFD, n = 9). Data is shown as mean ± standard deviation or median (minimum-maximum).
a,b,c
Mean values with unlike superscript letters were significantly different (p < 0.05). a:C vs. HFD or C vs. FO-HFD or C vs. KO-HFD, p < 0.05; b: HFD vs. FO-HFD, or HFD vs. KO-HFD, p < 0.05; c: FO-HFD vs. KO-HFD, p < 0.05.
†
p was calculated by the One-way Anova test, and Bonferroni test was performed for post-hoc analysis.
‡
p was calculated by Kruskall Wallis test, and Mann Whitney U test was performed for post-hoc analysis.
