Changes in post-dialysis systolic blood pressure, and prescription of antihypertensive agents during the study. Patients with post-dialysis SBP ≥ 140 mmHg (n = 139) at baseline (0 month): changes in post-dialysis SBP (a), and changes in DDD (b); Patients with post-dialysis SBP < 140 mmHg (n = 168) at baseline: changes in post-dialysis SBP (c), and changes in DDD (d). Abbreviations: C-HD, conventional haemodialysis; E-HD, electrolyzed water haemodialysis; SBP, systolic blood pressure; DDD, daily defined dose of antihypertensive agents. (a,c) There were significant differences in post-dialysis SBP (6 months; p < 0.05), and DDD (6, 12, 18 months; p < 0.05, respectively) between the two groups. (b,d) No differences were observed in post-dialysis SBP or DDD between the two groups.
