^aData are displayed as counts (%) or median [range].

^bP-value of difference in median time on dialysis between groups (Kruskal–Wallis test). Reference date: prevalent use rates were recorded at each 1 January from 2001 to 2006 for the second half of the study period.

^cPatients with >1 year interruption of HD due to transplantation were excluded from the analysis of time on HD: 2003: 1 AVF; 2004: 1 AVF; 2005: 2 AVF, 2 AVG; 2006: 3 AVF, 1 AVG. AVF, native arterio-venous fistula; AVG, arterio-venous graft; PC, permanent catheter.
