  1. aIn patients who had the event
  2. bSubdistribution hazard ratios of kidney transplantation were adjusted for gender, age, region (as strata), year of dialysis initiation, history of diabetes, peripheral arterial disease, serum albumin, panel reactive antibody level, blood group, temporary inactive status, and ownership of the nephrology facility
  3. cSubdistribution hazard ratios of death before kidney transplantation included a time interaction term for dialysis modality and were adjusted for gender, age, region (as strata), history of diabetes, peripheral arterial disease, previous transplantation (kidney excluded), number of cardiovascular comorbidities (as strata), mobility status, and serum albumin. These were not estimated for the group awaiting living-donor kidney transplant because of the small number of events
