Values expressed as mean value ± standard deviation or percentage (prevalence) and confidence interval (95%). SBP, DBP, and PP: systolic, diastolic, and pulse blood pressure, respectively. Hypertension: diagnosed hypertension and/or hypertensive levels during study. A was accepted as statistically significant.
