In this study, A Randomized, Controlled Trial of Early versus Late Initiation of Dialysis, by Cooper et al., adults with progressive chronic kidney disease and an estimated glomerular filtration rate between 10 and 15 ml per minute per 1.73 m2 (stage V chronic kidney disease) were randomly assigned to early or late initiation of dialysis. Early initiation of dialysis was not associated with an improvement in survival or clinical outcomes. (Via the NEJM.)
