  1. Footnotes: Each model was adjusted for individual characteristics evaluated at T1 (age group at eligibility, gender, BMI, smoking habits, daily alcohol intake, leisure time physical activity, diabetes, hypercholesterolemia), for treatment for hypertension at T1 and T2, employment at T1 and T2, and educational attainment, and initial BP level (for the whole sample)
  2. Significance of p-value < 0.5 are set in bold
