Odds ratio of dietary adherence for blood pressure control by sex and age group among adults with known hypertension. 1Odds ratio was adjusted for age, duration of hypertension, comorbid status of cardiometabolic diseases such as stroke, myocardial infarction, angina pectoris, diabetes, or dyslipidemia, and family history of hypertension, obesity, smoking, drinking, walking, and antihypertensive drug treatment. 2Dietary adherence was divided into ‘non-adherent’ (> 2400 mg sodium intake and low quartiles (Q1-Q3) of KHEI score), ‘slightly adherent’ (either ≤2400 mg sodium intake or highest quartile (Q4) of KHEI score), and ‘highly adherent’ (≤ 2400 mg sodium intake and highest quartile (Q4) of KHEI score). * < 0.05 of p-value for OR for blood pressure control compared with not-adherent men in each age group
