Univariate and multivariate Cox's proportional hazard analysis of variables for mortality in peritoneal dialysis patients

^*Covariates for serum albumin included age, Davies risk index, CRP, and edema index. Covariates for all other variables included age, Davies risk index, OPNI, CRP, and edema index; ^†High edema index tertile was defined as an extracellular water/total body water > 0.410 and low total lymphocyte tertile was defined as < 1,275/mL. HR, hazard ratio; CI, confidence interval; OPNI, Onodera's prognostic nutritional index; CRP, C-reactive protein.
