* p-value < 0.05
^aAdjusted 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, antihypertensive drug treatment, HEI score, and sodium intake
^bDietary 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). The OR 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, and antihypertensive drug treatment
