Randomized controlled trials in PD

Automated peritoneal dialysis; peritoneal dialysis solutions The publication of a systematic review comparing continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD) in this issue of NDT is very timely [1]. The growth in APD relative to CAPD has been striking over the past decade. Lifestyle factors, in particular, have resulted in more than half of new PD patients in North America using a cycler [2]. Similar trends have been seen in Europe and Japan. This move to APD was initially accom-panied by the notion that the therapy was probably superior in terms of its ability to provide higher doses of dialysis and more effective fluid removal [3]. There was also the suggestion, from a randomize
