After an adjustment for age, sex, coronary artery disease, total protein, alkaline-P, cholesterol, PTH, MAP, dialysis treatment time, insulin and analogues, and antiplatelets, adjusted HRs for high IVCD patients were 2.88 (95% CI 1.06–7.89) and 3.42 (95% CI 1.73–6.77) for all-cause mortality and MACE-event mortality, respectively. The gene discussed is PTH; the disease is coronary artery disorder.
