Multivariable Cox regression analyses for all-cause, cardiovascular, and infection-related mortality.

TA-Na, time-averaged serum sodium; HR, hazard ratio; CI, confidence interval. Model 1 adjusted for epidemiologic parameters including age, sex, body mass index, and Charlson Comorbidity Index score. Model 2 adjusted for all model 1 parameters plus medication including dose of furosemide, use of icodextrin, and use of high glucose dialysate. Model 3 adjusted for all model 2 parameters plus dialysis dose including peritoneal dialysis ultrafiltration (PDUF) and total Kt/V urea. Model 4 adjusted for all model 3 parameters plus malnutrition-inflammatory parameters including serum potassium, serum bicarbonate, serum albumin, serum ferritin, C-reactive protein (CRP), residual glomerular filtration rate (GFR), normalized protein catabolic rate (nPCR), and percentage of lean body mass (%LBM). Laboratory (serum sodium, potassium, bicarbonate, albumin, ferritin, and CRP) and dialysis-specific (PDUF, Kt/V urea, residual GFR, nPCR, %LBM) parameters are given as time-averaged values.Multivariable Cox regression analyses for all-cause, cardiovascular, and infection-related mortality.
