Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Willing and able to comply with all study procedures, visit schedules, and restrictions. Exclusion Criteria: 1. Diagnosed with Stage 1 Hypertension (SBP more than 139 mmHg or DBP more than 89 mmHg or Stage 2 Hypertension as per JNC 7 and WHO guidelines 2.
