Comparison of all-cause mortality among the five dialyzer type groups using Cox proportional hazards regression. The circles indicate the hazard ratios, and the bars correspond to 95% confidence intervals. Model 1 was adjusted for basic factors, including age, sex, dialysis vintage, the presence or absence of diabetes mellitus, and the presence or absence of cardiovascular complications. Model 2 was adjusted for dialysis-related factors, including Kt/V values, β2-microglobulin levels, and systolic and diastolic blood pressure values, in addition to basic factors. Model 3 was adjusted for basic factors, dialysis-related factors, and nutrition- and inflammation-related factors, including body mass index, serum albumin, urea nitrogen, creatinine, hemoglobin, phosphate, calcium, intact parathyroid hormone, normalized protein catabolic rate, and C-reactive protein levels
