Fig 2. Competing risk model for patient death and technical failure of elderly (≥65 years) patients undergoing peritoneal dialysis (PD), as compared with younger PD patients and elderly hemodialysis (HD) patients.

A. Comparison of patient death in younger (<65 years) patients undergoing PD. Transplantation and technical failure were considered competing risk events when examining patient death. B. Comparison of technical failure in younger (<65 years) patients undergoing PD. Patient death and transplantation were considered competing risk events when examining technical failure. C. Comparison of patient death in elderly patients undergoing HD. Transplantation was considered a competing risk event when examining patient death because there was no transplantation as a competing event in elderly patients.
