TA-Na, time-averaged serum sodium; SHR, subdistribution hazard ratio; CI, confidence interval. Adjustments in model 1: Demographic and clinical parameters including sex, body mass index, Charlson Comorbidity Index score, anti-hypertensive medications; model 2: model 1 plus dialysis-specific parameters including use of icodextrin, use of high glucose dialysate, peritoneal dialysis ultrafiltration, total Kt/V urea, normalized protein catabolic rate, and percentage of lean body mass; model 3: model 2 plus laboratory parameters including serum hemoglobin, serum albumin, calcium, phosphorus, potassium, bicarbonate, serum ferritin, C-reactive protein, and residual renal function.Multivariable Cox regression analyses for the risk of new-onset cardiovascular events.
