<qa>  What is the blood pressure of the trial participants?Trial participants were generally healthy adults, aged 30 years and older, with a systolic blood pressure of 120 to 159 mm Hg or a diastolic blood pressure of 80 to 99 mm Hg. This range includes individuals with prehypertension systolic, 120-139 mm Hg or diastolic, 80-89 mm Hg and stage 1 hypertension systolic, 140-159 mm Hg or diastolic, 90-99 mm Hg. Prehypertensive individuals are a group at high risk of developing hypertension and CVD, justifying special attempts to lower blood pressure.
