IL7 and peripheral arterial disease: Although FGF-23 and TRAIL-R2 achieved lower p-values (< 0.001) in the PAD vs. non-PAD comparison relative to IL-7 (p = 0.001), there was no statistically significant association between FGF-23 and TRAIL-R2 and 2-year MALEs in the HR analysis (p values of 0.484 and 0.635, respectively), while there was a statistically significant association between IL-7 and 2-year MALEs (p = 0.007).
