  1. Previously diagnosed (known hypertensives) whose BP was ‘normal’ at study evaluation and thus BP not categorized as hypertension: n = 56 using JNC7 and n = 26 by ACC/AHA 2017 (multiplied by 3.5% to accommodate 187 missing data = 58 and 27 respectively). Prevalence adjusted to include additional known hypertensives would be as follows: ACC/AHA = 3030/5365 i.e. 56.5% and 1531/5365 = 28.5%
