  1. HD hemodialysis, PD peritoneal dialysis, eGFR estimated glomerular filtration rate, HR hazard ratio, 95% CI 95% confidence intervals.
  2. Model-1 was adjusted for age and gender.
  3. Model-2 was adjusted as Model-1 + heart failure and diabetes.
  4. Model-3 was adjusted as Model-1 + mobility.
  5. Model-4 was adjusted as Model-1 + dialysis modality and baseline eGFR.
  6. Model-5 was adjusted for all variables in previous models.
  7. NS Not Significant (with p > 0.1).
