Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Whether the difference in blood pressure change before and after antihypertensive treatment, as measured by the cuff-based auscultatory method and by Alysis-001 (calculated from the left forearm device), is 5 +/- 8 mmHg (mean +/- SD or less for both systolic and diastolic blood pressure. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Difference in systolic and diastolic blood pressure values measured by the cuff-based auscultatory method and by Alysis-001 (left forearm device) at enrollment and after 4 weeks of treatment 2. Difference in 24-hour systolic and diastolic blood pressure changes before and after antihypertensive treatment as measured by ABPM and Alysis-001 3. Difference in 24-hour systolic and diastolic blood pressure values measured by ABPM and Alysis-001 at enrollment and after 4 weeks of treatment 4. Difference in daytime and nighttime systolic and diastolic blood pressure changes before and after antihypertensive treatment as measured by ABPM and Alysis-001 at enrollment and after 4 weeks of treatment 5. Difference in daytime and nighttime systolic and diastolic blood pressure values measured by ABPM and Alysis-001 at enrollment and after 4 weeks of treatment 6. Difference in systolic and diastolic blood pressure changes before and after antihypertensive treatment, stratified by antihypertensive drug type, as measured by the cuff-based auscultatory method and by Alysis-001 7. Comparison of 24-hour systolic and diastolic blood pressure changes before and after antihypertensive treatment, stratified by antihypertensive drug type, as measured by ABPM and Alysis-001 8.
