Hypertension was defined as systolic blood pressure of at least 140 mmHg and/or diastolic blood pressure of at least 90 mmHg and/or the use of antihypertensive medication. Control¹ is the rate among individuals with hypertension. Control² is the rate among individuals under hypertension treatment. Because the accessibility of data varies from country to country, if the data is not accessible, the corresponding field is left blank. If one of the two control rates was not accessible, it was calculated using the following equation:
\(\frac{\mathrm{Control rate among individuals with hypertension }(\mathrm{\%})}{\mathrm{Treatment rate }(\mathrm{\%})} =\mathrm{ Control rate among individuals under hypertension treatment }(\mathrm{\%})\)

^aThe all-age groups represent the general population in each country and were defined as follows: ≥ 18 in the United States, Korea, China, and Greece, ≥ 20 in Japan, and 15–49 in Ghana; ^bFor all-age groups, prevalence was age-standardized except for Satoh et al. [19]
