aOnly first renal transplants were included. Technique failure was considered to occur upon a switch from PD to hemodialysis. RR was estimated using Poisson regression based on an as-treated analysis, adjusted for age, gender, race, primary renal diagnosis follow-up time, and type of PD (i.e., CAPD/CCPD, IPD).
