Fig. 2 — Cumulative incidence^# of vascular access conversion to functional AV access. (a) Nonfunctional AV access group and (b) Catheter only group at hemodialysis initiation. ^#Competing risks considered were renal transplantation, peritoneal dialysis switch, dialysis weaning, and death, whichever came first. Gray’s test P-value (nonfunctional AV access versus catheter only): conversion to functional AV access, peritoneal dialysis switch, dialysis weaning, and death, <0.0001; renal transplantation, 0.04. Abbreviation: AV arteriovenous. *Cumulative incidence of peritoneal dialysis and dialysis weaning in the nonfunctional AV access group: 0.8 and 0.7%, respectively
