What it does not show
The follow-up was only one month, so it cannot show whether the gains last or affect blood pressure. The primary outcomes were knowledge, attitude and practice scores, not blood pressure control. The study was done in one hospital, and participants were first selected by convenience sampling. The analysis included 30 participants in each group after 10 of 70 withdrew. The questionnaire was made by the researchers, although content validity and reliability were checked. The control group also received discussion sessions and booklets, so the effect is against limited education, not no education. The assistant completing the questionnaire did not know the study course, but patients and the researcher were familiar with it.
The easy way to misread this
Do not conclude that the program lowers blood pressure or prevents heart problems. The primary outcomes were knowledge, attitude and practice scores one month after education, not blood pressure control.
