Fig 1 This figure shows the Kaplan-Meier curves of primary patency rates of TBB fistulas and Vectra grafts. Primary patency of TBB fistulas and the Vectra graft was equal (P = .62). Error bars of the survival curves represent standard error, while the number of patients at risk at each interval is also shown.

Fig 2 This figure shows the Kaplan-Meier curves of primary assisted patency rates of TBB fistulas and Vectra grafts. Primary assisted patency was significantly reduced in Vectra grafts, compared with TBB fistulas P = .033. Error bars of the survival curves represent standard error, while the number of patients at risk at each interval is also shown.

Fig 3 This figure shows the Kaplan-Meier curves of functional secondary patency rates of TBB fistulas and Vectra grafts; equivalent rates at 12 and 18 months were observed. Error bars of the survival curves represent standard error, while the number of patients at risk at each interval is also shown.

Fig 4 This figure demonstrates the negative predictive value of arterial anastomotic stenosis detected and treated with angioplasty at any stage during Vectra graft’s life on secondary patency rates; these were 60.6% at 12 and 18 months compared with 92.4% for grafts that had no interventions performed (P = .014) and 95.5% for patients that had any intra-graft, venous outflow, draining or central vein stenoses treated with angioplasty at any stage (P = .010). Error bars of the survival curves represent standard error, while the number of patients at risk at each interval is also shown.
