  1. Bold shows are statistically significant
  2. The model is adjusted for age, sex, and the first ten principal components
  3. Hypertension is defined as systolic/diastolic blood pressure of 140/90 mmHg or higher measured at a community-support center and/or self-reported treatment for hypertension
  4. Lifestyle is categorized as ideal (having at least three ideal lifestyle factors), poor (having 0–1 ideal lifestyle factors), intermediate (having 2–3 ideal lifestyle factors)
  5. Lifestyle includes the following factors: obesity, defined as BMI ≥ 25.0 kg/m2 based on the Western Pacific Region of World Health Organization criteria in Japanese individuals, high Na/K ratio, defined as ≥4.0, insufficient regular physical activity, defined as not meeting the American Heart Association recommendations of at least 150 min of moderate activity per week or 75 min of vigorous activity per week, smoking, defined as ex-smoker or current smoker, drinking, defined as ex-drinker or current drinker
  6. Genetic risk is classified based on the tertile of polygenic risk score
  7. CI confidence interval, RR relative risk
