Percentage of positive cells expressing Caspase-3 in the dentate gyrus of the hippocampus. A one-way ANOVA test shows a significant treatment effect in Caspase-3 expression [F(3,20) = 6.616; P < 0.05]. Significant differences between groups derived from Bonferroni post hoc are shown. *: P < 0.05 vs. control. a: P < 0.05 vs. ketogenic diet. b: P < 0.05 vs. time-restricted diet. The percentage of positive cells was significantly lower in the TRD group than those in other groups
