Numbers inside the columns indicate the number of animals. (A) Results of old animals. + : p < 0.05 vs zero, singe sample t-test, control: t(11) = 2.76, STZ: t(8) = 0.67, ns.), effect size: 0.55.Three animals in the STZ group died before the test was carried out (B) Results of young animals. *: p < 0.05 vs control, unpaired t-test, t(20) = 2.24), effect size:0.96.
