ARIC indicates Atherosclerosis Risk in Communities Study; BP, blood pressure; CHD, coronary heart disease; HF, heart failure; IRD, incidence rate differences; JNC 8, the 2014 Guidelines for the Management of High Blood Pressure from the Eighth Joint National Committee.
Events reduced calculated as IRDijk×(proportionl−proportionm) where i, j, and k index race, gender, and 5‐year age categories, proportion is the race‐specific proportion of BP above goal36 pre‐ (l subscript) and post (m subscript)‐ intervention, per 100 000 person years.
