The aim of the present study was to investigate the associations of serum fetuin-A and OPG levels with carotid to femoral PWV (cfPWV), a marker of arteriosclerosis [13], and common carotid IMT (ccIMT), a marker of early atherosclerosis [14], in a group of maintenance HD patients. The gene discussed is TNFRSF11B; the disease is atherosclerosis.
