APD use over time: the proportion of incident Australian PD patients using APD according to time spent on PD during the period from 2003 to 2011. APD, automated peritoneal dialysis; CAPD, continuous ambulatory peritoneal dialysis; PD, peritoneal dialysis.

Association between APD (versus CAPD) and peritonitis-associated outcomes in incident Australian PD patients during the period from 2003 to 2011. All estimates are adjusted for previous RRT before PD, age, race, body mass index, diabetes mellitus, coronary artery disease, cigarette smoking, and cerebrovascular disease. Outcome of first infection also adjusted for organism. 95% CI, 95% confidence interval; HD, hemodialysis; HR, hazard ratio; IRR, incidence rate ratio; OR, odds ratio.
