Note: The values presented in the column “p-value” represent the overall difference between the three groups; bold font indicates a significant difference between groups (p < 0.05); post-hoc differences in comparisons between individual groups are denoted below as * = significant difference from non-PAD control, p < 0.05; † = significant difference from IC, p < 0.05.
