ALB and hydrops fetalis: Pre-dialysis (HF-HD: 3.95 ± 0.21 g/dL, post-OL-HDF: 4.09 ± 0.29 g/dL, and MCO-HD: 3.91 ± 0.29 g/dL), post-dialysis plasma albumin (HF-HD: 4.18 ± 0.50 g/dL, post-OL-HDF: 4.18 ± 0.50 g/dL, and MCO-HD: 4.09 ± 0.43 g/dL), and RRs of albumin (HF-HD: −9.77 ± 11.09%, post-OL-HDF: −5.26 ± 7.73%, and MCO-HD: −5.50 ± 9.17%) were not significantly different among the three different dialysis modalities.
