Fig. 4From: Amelioration of hemodialysis-induced oxidative stress and fatigue with a hemodialysis system employing electrolyzed water containing molecular hydrogenTemporal course of changes in NRS for subjective fatigue. Pre: control hemodialysis at 2–4 weeks before commencement of E-HD. E-HD: hemodialysis employing electrolyzed water. Non-fatigue (n = 36): NRS < 3 at control HD (Pre). Fatigue (n = 27): NRS ≥ 3 at control HD (Pre). *p < 0.05 vs. pre. **p < 0.01 vs. preBack to article page
