  1. Abbreviations: ACE, angiotensin-converting enzyme; ALT, alkaline phosphatase; ANOVA, analysis of variance; ARB, angiotensin II receptor antagonists; DBP, diastolic blood pressure; GDROP<15 mm Hg,, patients with their SBP drop <15 mm Hg after hemodialysis; GDROP⩾15 mm Hg, patients with their SBP drop ⩾15 mm Hg; GHTN, patients with their SBP increase ⩾10 mm Hg after hemodialysis; SBP, systolic blood pressure.
