(A–C) Frailty score of male mice (A) was tracked throughout the experiment between 20 and 24 months of age (n=10–13/group, p-value represents the result of the indicated 2-way mixed-effects analysis). (B–C) Selected individual frailty categories, presented as the average of scores during the 3rd and 4th month of the experiment. (A-C) n=10–13/group at the beginning of the experiments, ANOVA followed by Dunnett’s test vs. Aged Control-fed mice. (D–E) Male rotarod (D) and inverted cling (E) performance were assessed between 22–23 months of age (n=8–11/group, ANOVA followed by Dunnett’s test vs. Aged Control-fed mice). (F–G) Male Barnes Maze Test performance at 24 months of age (F). n=7–10/ group, p-value represents the effect of diet in the indicated 2-way ANOVA, acquisition time only. (G) Barnes Maze Test acquisition trial duration with loitering (test on loitering time only, ANOVA followed by Dunnett’s test vs. Aged Control-fed mice). (H–J) Frailty score of female mice (H) was tracked throughout the experiment between 20 and 24 months of age (n=10–11/group, p-value represents the effect of diet in the indicated 2-way ANOVA). (I–J) Selected individual frailty categories, presented as the average of scores during the 3rd and 4th month of the experiment. (H–J) n=10–11/group at the beginning of the experiments, ANOVA followed by Dunnett’s test vs. Aged Control-fed mice. (K–L) Female rotarod (K) and inverted cling (L) performance were assessed between 22–23 months of age (n=8–11/group, ANOVA followed by Dunnett’s test vs. Aged Control-fed mice). (M–O) Female Barnes Maze Test performance at 24 months of age (M). n=8–10/ group, p-value represents the effect of diet in the indicated 2-way ANOVA, acquisition time only. (O) Barnes Maze Test acquisition trial duration with loitering (test on loitering time only, ANOVA followed by Dunnett’s test vs. Aged Control-fed mice). *p<0.05, **p<0.01, ***p<0.001, ****p<0.0001.
