Figure 1

Boxplot illustrating the levels of normalized uFABP3/uCr among non-PAD controls (n = 65) and PAD patients stratified based on their ABI values (mild PAD: 0.89–0.75, n = 11; moderate PAD: 0.74–0.50, n = 29; severe PAD: < 0.50, n = 25). Significant difference in median uFABP3/uCr levels was noted between the moderate and severe PAD subgroups compared to non-PAD group, (p-value < 0.001). Values displayed in figure represents median uFABP3/uCr levels values in each subgroup. * p-value < 0.05 compared to non-PAD group.
