  1. AVF arteriovenous fistula, HD haemodialysis, PD peritoneal dialysis, eGFR estimated glomerular filtration rate. Incident patient means a patient starting dialysis for the first time; prevalent refers to a patient who has been on a form of renal replacement therapy before but who intends to start dialysis due to a failing transplant
  2. *Ethnicity codes taken from those used in UK renal units
