Change from baseline in (A) mean sitting systolic blood pressure (SBP) and (B) mean sitting diastolic blood pressure (DBP) (mm Hg) at the end of study 2 in elderly (65 years or older) patients. The number of patients in each treatment group ranged from 51 to 70. The SD from the mean (systolic/diastolic, expressed in mm Hg) in each treatment group was as follows: placebo, 15.2/8.8; valsartan 160 mg, 12.7/7.5; valsartan 320 mg, 16.8/10.2; amlodipine 10 mg, 11.2/6.6; amlodipine 10 mg + valsartan 160 mg, 12.7/8.0; and amlodipine 10 mg + valsartan 320 mg, 12.7/8.2.
