  1. Multivariate analysis was performed, with age (< 60, 60 s, or ≥ 70), gender, primary disease (chronic glomerulonephritis, diabetes mellitus, nephrosclerosis, others), duration of dialysis (< 1 year, 1 to < 5 years, 5 to < 10 years, 10 to < 15 years, or ≥ 15 years), BMI, albumin, blood urea nitrogen, creatinine, CRP, white blood cell count, hemoglobin, and platelet count as independent variables
  2. All data show hazard ratio for every 1 increase in value
  3. BMI body mass index, Alb albumin, BUN blood urea nitrogen, Cr creatinine, CRP C-reactive protein, WBC white blood cell count, Hb hemoglobin, PLT platelet count
