In a Kidney International article, Avram et al. (A-27) reported on a study involving 529 hemodialysis patients and 326 peritoneal dialysis patients. They found that at baseline 249 subjects in the hemodialysis treatment group were diabetic, while at baseline 134 of the subjects in the peritoneal dialysis group were diabetic. Is there a significant difference in diabetes prevalence at baseline between the two groups of this study? Let a ¼ :05. What does your finding regarding sample significance imply about the populations of subjects?
