Table 2 Adjusted mean years and median years from normal BP to stage 2 hypertension for participants by courses

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

Results Mean progression years from normal BP to stage 2 HTN (mean±SD) Median progression years from normal BP to stage 2 HTN P-value
Course A (n=695) 8.6±2.6 8.97 <  0.01
Course B (n=430) 6.1±2.9 5.65  
Course C (n=2378) 7.5±2.8 7.61  
Course D (n=1501) 3.2±2.0 2.34  
  1. The p-value for ANCOVA (analysis of covariance) test adjusting for age is represented
  2. BP blood pressure, HTN hypertension
  3. Course A: normal BP → elevated BP → stage1 HTN → stage2 HTN
  4. Course B: normal BP → elevated BP → stage2 HTN
  5. Course C: normal BP → stage1 HTN → stage2 HTN
  6. Course D: normal BP → stage2 HTN
