a Systolic pressure <140 mmHg and diastolic pressure <90 mmHg between treated individuals.
b PR (95%CI): crude prevalence ratio (95% confidence interval), estimated by the Poisson regression model.
c PR (95%CI): adjusted prevalence ratio (95% confidence interval) for all variables listed in the table, estimated by the Poisson regression model.
%: Percentages estimated considering the sample parameters and the weights of the individuals.
