  1. In addition to age, gender, hemodialysis duration, and diabetic nephropathy, possible factors that showed P less than 0.15 in univariate analysis such as protein catabolic rate, creatinine generation rate, hemoglobin, albumin, uric acid, mean sodium, and phosphate were chosen in full model analysis
  2. Final model analysis was done with age, gender, hemodialysis duration, diabetic nephropathy and the variables with P less than 0.1 in full model analysis such as hemoglobin, and mean sodium
  3. DN diabetic nephropathy, HD duration hemodialysis duration, HR hazard ratio, 95% CI 95% confidence interval
