Why the study?
Does a proportional feedback system improve self-control of systolic blood pressure in normotensive subjects compared to binary or no feedback?

May support proportional feedback for SBP self-control in normotensives; leaves open translation to hypertension or clinical outcomes.
Does a proportional feedback system improve self-control of systolic blood pressure in normotensive subjects compared to binary or no feedback?
A closed-circuit television-based proportional feedback system is effective in teaching normotensive individuals to self-control and lower their systolic blood pressure.
