Interventions/Control_1 Enrolled patients were randomly assigned with a two-by-two factorial design to either 1 of 2 levels of pre-dialytic mean arterial pressure (BP) goals, 105 to 110 mmHg (usual BP group, around 140/90 mmHg) or 95 mmHg or less (lower BP group, equal to or less than 135/75 mmHg). To achieve the target pre-dialysis MAP goals, we conducted multiple and intensive nonpharmacological and pharmacological treatment, including request of recording of home blood pressure monitoring and diet-diary with specialists' consultation, repeated confirmation of patients' dry weight, a longer dialysis session including ultrafiltration, add-on of open-label antihypertensive agents (alfa-adrenergic antagonists, direct-acting vasodilator, beta-adrenergic antagonists, centrally acting adrenergic agents, and alfa--methyldopa), correction of anemia (less than 33 percent), and treatment of serum calcium and phosphorus abnormalities (surgical treatment, if necessary).
Interventions/Control_2 Enrolled patients were randomly assigned with a two-by-two factorial design to initial antihypertensive treatment with either amlodipine or trandolapril. ACE inhibitors (or ARBs) or CCBs were stopped 2 weeks before randomization. Initial dose of trandolapril of 0.25 mg or amlodipine of 2.5 mg per day were administrated at inter-dialysis night and then were up-titrated individually to be maximum tolerated. To keep the drug class intervention blinded, the study drug was prepared separately from other drugs and placed within opaque paper envelop, which obscured the drug inside.

Key inclusion criteria Hypertensive patients, 23 to 70 years of age, all Japanese, who were undergoing outpatient hemodialysis thrice weekly for three or more months were enrolled between January 1996 and December 1999. Hypertension was defined as averaged office pre-dialysis BP at sitting position of 150/90 mm Hg or more with or without antihypertensive medications for a minimum of three month before randomization.
Key exclusion criteria patients with preserved residual renal function (urine volume of more than 500 mL per day), pre-dialysis BP of less than 140/60 mm Hg, unstable homodynamic during hemodialysis therapy, a history of drug-allergy, accelerated or malignant hypertension within six months, secondary hypertension, severe systemic diseases, including cardio-,cerebro- and peripheral vascular, pulmonary, and gastrointestinal and hepatic diseases.
