  • 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.
