Figure 8: The relationship between the level of Nrf2 and the levels of biomarkers of antioxidant factors. (a) The relationship between the level of Nrf2 and the level of SOD. (b) The relationship between the level of Nrf2 and the level of GSH. (c) The relationship between the level of Nrf2 and the level of ALT. (d) The relationship between the level of Nrf2 and the level of AST. Spearman’s rank correlation test was performed to compare two variables. There is a strong negative association if the value of rho falls between −1 and −0.5. There is a strong positive association if the value of rho falls between 0.5 and 1.
