Statistical analysis
In this study, the statistical analysis involved the use of an independent t-test to assess the differences in quantitative variables between the intervention and control groups. The homogeneity of qualitative variables was evaluated using the Chi-square and Fisher’s exact test. Mean and standard deviation were used to report and describe the quantitative variables, while frequency and percentage were employed for qualitative variables. Levene’s test was conducted to check the equality of variances for the investigated variables, including health literacy score, medication adherence, and systolic blood pressure score, between the intervention and control groups. The null hypothesis assumed equal variances between the two groups. Subsequently, the independent
