^aData are displayed as counts (%) and median [range], P-value of difference between male and female (Fisher's exact test). Reference date: prevalent use rates were recorded at each 1st January from 2001 to 2006 for the second half of the study period. AVF, native arterio-venous fistula; AVG, arterio-venous graft; PC, permanent catheter.
