The data were analyzed using an ANOVA test and Post hoc Bonferroni to evaluate statistical significance between groups. If the normality or equal variance test was violated, a comparison was made using the non-parametric Mann–Whitney U-test. Chi square test was used for categorical data. The results are represented as the means ± SEM. ^&p < 0.05 vs. CKD4-5; *p < 0.05 vs. hemodialysis; #p < 0.05 vs. kidney transplantation; not applicable (n.a.).
