#P-value for Inter-group comparison between the two groups (Mann-Whitney test).
##Overall P-value for Intra-group comparison between the different time intervals (Kruskal-Wallis test). - Capital letters for intra-group comparison between the different time intervals (Mann-Whitney test) and the medians with different superscripts are statistically significant different at P ≤ 0.05.
**Highly significant at P ≤ 0.001, *Statistically significant at P ≤ 0.05.
NS Non-significant P > 0.05.
