The three stages of the hypertension cascade of care showing losses that occur at different points (adapted from Berry et al, 2017 [16]). *Most studies defined hypertension by a SBP > =140 mmHg; and/or a DBP > =90 mmHg; or by a self-reported treatment with antihypertensive medication. A few studies used different cut-off points for SBP and DBP such as SBP > =140 mmHg and/or DBP > =80 mmHg; or SBP > =160 mmHg and/or DBP > =95 mmHg.
