Body weights of streptozotocin-induced diabetic rats (STZ) and sham control (CTRL) rats before, and at 3, 5, 7, 14, 21 and 28 days after experimental model induction via systemic drug injection.

<p>Both groups increased their body weights over time (Repeated measures ANOVA, p<0.0001), whereas the STZ group consistently showed lower weight gain than the CTRL group after systemic drug administration (Post-hoc Sidak’s multiple comparisons correction tests, *p<0.0001).
