Changes in body weight of rats

Groups	1st week	16th week	21st week	P value†
ND	219 ± 10.83	276 ± 26.72	289 ± 29.80	0.001
ND + vitamin D	225 ± 22.09	278 ± 27.38	256 ± 26.90	0.001
HFD	219 ± 13.27	403 ± 4.13	425 ± 3.71	0.001
HFD + vitamin D	225 ± 13.77	340 ± 8.7	381 ± 7.80	0.001
F values	0.170	135.097	147.026
‡ P value	0.69	0.001	0.001

Data are expressed as mean ± SD. Statistical differences between groups were assessed by one-way ANOVA followed by Tukey’s test for Post Hoc analysis. Intra group comparisons of body weight were performed by repeated measure analysis

HFD high fat diet, ND normal diet

^† P value and ^‡ P value indicated intra group and inter group differences respectively. ^‡The significant difference in comparison of the weight of 16th week was between ND versus HFD and HFD + Vit D, ND + Vit D versus HFD and HFD + Vit D and HFD versus ND. Whereas in comparison of weight of 21st week between groups all of the inter group comparisons were significant. P < 0.05 was considered as statistically significant. N = 20 in each group
