Table 1. Body weight and body weight variation from days 1 to 30, 30 to 45 and 45 to 60 in water control group (water + saline), HFD control group rats (HFD + saline), NTG-injected rats (water + NTG), and HFD NTG-injected rats (HFD + NTG), with or without n-3 supplementation (water + n-3; HFD + n-3; n-3 + NTG; HFD + n-3 + NTG).

Data are presented as means ± SEM of 10 to 12 rats per group for body weight (two-way ANOVA followed by Tukey’s post hoc test; one-way ANOVA followed by uncorrected Fisher’s LSD’s post hoc; or Kruskal-Wallis followed by uncorrected Dunn’s post hoc test). a, P<0.05 water + saline vs. HFD + saline; b, P<0.05 water + saline vs. water + NTG; d, P<0.05 water + n-3 vs. water + n-3 + NTG; f, P<0.05 HFD + saline vs. HFD + NTG; h, P<0.05 HFD + n-3 vs. HFD + n-3 + NTG; i, P<0.05 HFD + NTG vs. HFD + n-3+ NTG; j, P<0.05 water + n-3 vs. HFD + n-3; k, P<0.05 water + NTG vs. HFD + NTG; l, P<0.05 water + n-3 + NTG vs. HFD + n-3+ NTG. BW, body weight; NTG, nitroglycerin; HFD, high fructose diet; SEM, standard error of the mean.
