Table 3 Summary of results from the bivariate linear mixed-effect model

From: The impact of a cardiovascular health awareness program (CHAP) on reducing blood pressure: a prospective cohort study

  Systolic blood pressure Diastolic blood pressure
  RR* 95% CI p value RR* 95% CI p value
High blood pressure at baseline
 Baseline 141.61 (138.56 144.74) <0.01 78.13 (75.99 80.32) <0.01
 Rate ratio 0.9921 (0.9905 0.9937) <0.01 0.9929 (0.9914 0.9944) <0.01
Not high blood pressure at baseline
 Baseline 120.44 (118.79 122.12) <0.01 69.93 (68.67 71.21) <0.01
 Rate ratio 0.9999 (0.9993 1.0004) 0.69 0.9996 (0.9990 1.0001) 0.11
  1. RR = rate ratio; CI = confidence interval.
  2. Rate ratio was expressed as the change of current blood pressure in 1 month.
  3. *The rate ratio was adjusted for all baseline risk factors.
