Values for continuous variables are given as mean ± standard deviation or median (25th, 75th percentile); values for categorical variables are given as count (percentage).
Percentages may not add to 100 due to rounding.
Values were missing for one patient for dialysate potassium, calcium and bicarbonate; two patients for ultrafiltration volume; one patient for blood flow and dialysate flow; 10 patients for dialysate temperature.
