GDF15 and peripheral arterial disease: Although the patients with PAD and the rs1054564 C allele had higher baseline GDF15 levels (4407.8 (2362.3–7044.5) versus 2814.4 (1699.8–5417.2) pg/mL, P = 0.280) and higher probability (40% versus 28.9%) of mortality during follow-up after EVI compared to those with the rs1054564 GG allele, the differences were not statistically significant.
