^ABCells sharing the same letter across a row did not differ significantly by Dunn’s post-hoc test with Bonferroni correction for multiple comparisons (adjusted α = 0.0083).

^XYCells sharing the same letter down a column, within a dietary group, did not differ significantly by Dunn’s post-hoc test with Bonferroni correction for multiple comparisons (adjusted α = 0.0083).

Kruskal–Wallis analyses were done on each row and each diet, separately for standard chow diet (SD) and western diet (WD).
