In this guideline Chronic Kidney Disease Stage 5 (CKD 5) includes pre-dialysis and transplant patients with eGFR < 15 ml/min/1.73m2  as well as patients on dialysis i.e.  CKD 5, CKD 5T and CKD 5D. This guideline is an updated version of the Renal  Association guidance developed by the same lead co-authors published in 2007 and is  based on a review of the literature between 2007 and 2010. Where evidence was  available from RCTs and systematic reviews recommendations were based on these
publications. Where there was a lack of evidence from high-quality studies, recommendations were based on the best available evidence taking in account the  previous clinical practice guidelines on evaluation of the potential kidney transplant  recipient from North America2 and the European Renal Best Practice (ERBP) guidelines  for renal transplantation。
