Data are presented as mean±SD. ΔD was the difference before and after treatment. p-values were calculated by paired t-tests, before and after treatment, in each group. When comparing the ΔD between groups A and B, the p-values were 0.026 for MDA and 0.804 for GSH. When comparing the ΔD between group A+C and group B, the p-values were 0.034 for MDA and 0.834 for GSH.
MDA, malondialdehyde; GSH, glutathione.
