^{a}Calculated by direct extrapolation from the truncated costing period for patients who died in year 1 to enable reporting as cost per patient-year at risk.↵

^{b}*P*< 0.001 comparing the log-transformed cost of catheter-only and graft patients using a two-sample*t*test.↵

^{c}*P*= 0.01 comparing the log-transformed cost per patient-year at risk of catheter-only and graft patients using a two-sample*t*test.
