  1. All values are expressed as number (percent) or mean ± SD; statistical analyses were performed for SLED versus CVVH. *One-tailed Wilcoxon test; **2 × 2 table Chi-Square test with Yates' correction. BP syst: systolic blood pressure; BP diast: diastolic blood pressure; SLED: sustained low efficiency dialysis; CVVH: continuous veno-venous hemofiltration.
