AHSG and atherosclerosis: While there were no associations of fetuin-A with IMT as a surrogate marker of atherosclerosis (r = -0.11, p = 0.2, Figure 1a), patients with an ABI < 0.9 had lower fetuin A levels than patients with an ABI 0.9-1.3 or > 1.3 (0.43 ± 0.10 vs. 0.52 ± 0.17 vs. 0.54 ± 0.18 g/L p = 0.05).
