Model 1, which included log adiponectin, in addition to age, body weight, percentage body fat, hemodialysis duration, presence/absence of DM, serum calcium and phosphate levels, log intact parathyroid hormone (PTH), and log hs-CRP as independent variables, showed that log adiponectin, in addition to the presence/absence of DM, emerged as a significant and independent factor associated with the presence of AAC (odds ratio: 9.76, 95% confidence interval [CI]: 1.13–84.36, p = 0.04). The gene discussed is PTH; the disease is diabetes mellitus.
