From: A longitudinal analysis of the progression from normal blood pressure to stage 2 hypertension: A 12-year Korean cohort

Results Remained as normal BP Remained as elevated BP Remained as stage 1 HTN Resulted as stage 2 HTN
40–49 years (n=15,527) 2204 (14.2) 1726 (11.1) 8566 (55.2) 3031 (19.5)

  1. Values are expressed as number and percentage (%)
  2. There were differences in the proportion of blood pressure levels by age groups in all final stages (p for trend < 0.01)
  3. BP blood pressure, HTN hypertension
