Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline to End of Study in the Mean Sitting Diastolic Blood Pressure (msDBP) | Baseline, End of Study (Week 8) | After the patient had been sitting for 5 minutes, systolic and diastolic blood pressures were measured 3 times using the automatic Blood Pressure monitor and appropriate size cuff. The repeat sitting measurements were made at 1-2 minute intervals and the mean of these 3 sitting blood pressure measurements was used as the average sitting blood pressure for that visit. The difference of the msDBP at baseline from the msDBP at 8 weeks was calculated using an Analysis of Covariance (ANCOVA) model with baseline as a covariate and treatment and region as two factors. |

Change From Baseline to End of Study in the Mean Sitting Diastolic Blood Pressure (msDBP)
After the patient had been sitting for 5 minutes, systolic and diastolic blood pressures were measured 3 times using the automatic Blood Pressure monitor and appropriate size cuff. The repeat sitting measurements were made at 1-2 minute intervals and the mean of these 3 sitting blood pressure measurements was used as the average sitting blood pressure for that visit. The difference of the msDBP at baseline from the msDBP at 8 weeks was calculated using an Analysis of Covariance (ANCOVA) model with baseline as a covariate and treatment and region as two factors.
