Mortality | 63.9% vs 63.4% (P = .94) | 58% vs 53% (P = .48) | 30.2 vs 53.2 (P = .002) | 55 vs 53% (P = .42) | 79% vs 63% (P = .13) |
Limitations | Single centre, significantly different baseline characteristics | Single centre, patients not surviving 24 h excluded, underpowered for mortality | Single centre, adequate effluent rates on CKRT, however creatinine levels remained higher than expected for the dose achieved | Single centre | Single centre, small body surface area of patients |
EHD, extended haemodialysis; CVVHDF, continuous veno-veno haemodiafiltration.
