Fig. 3. Multivariate analyses of mortality in subgroups according to dialysis modality, age categories, and diabetes. (A) After adjusting for age, sex, type of Healthcare Security System, and modified CCI, patients initiating either HD or PD in 2008 had significantly lower mortality. (B) After adjusting for age, sex, type of Healthcare Security System, dialysis modality, and modified CCI, the statistical significance of this difference was lost only among non-diabetic patients aged less than 65. PD, peritoneal dialysis; HD, hemodialysis; ND, non-diabetic; DM, diabetes mellitus; HR, hazard ratio; CI, confidence interval; CCI, Charlson Comorbidity Index.
