Comparison of all-cause mortality between the hemodialysis (HD), low-volume intermittent infusion hemodiafiltration (I-HDF), and high-volume I-HDF groups using Cox proportional hazards regression. The circle indicates the hazard ratio, and the bars correspond to 95% confidence intervals. Basic factor includes gender, age, duration of dialysis, presence or absence of diabetes, and cardiovascular disease. Nutrition- and inflammation-related factors include body mass index, systolic and diastolic blood pressures and heart rate at predialysis, serum albumin, hemoglobin, phosphate, calcium, intact parathyroid hormone, C-reactive protein levels, normalized protein catabolic rate, and percentage of creatinine generation rate. β2MG, β2-microglobulin; HD, hemodialysis; I-HDF, intermittent infusion hemodiafiltration
