Data analysis and processing
All the self-administered questionnaires were checked manually for completeness and consistency. The collected data coded and entered to SPSS version 24, STATA 14, and RevMan5.3 for data processing and analysis. Simple descriptive statistics such as a frequency distribution and percentages performed to describe the demographic and socioeconomic. Mann Whitney U test and Independent Sample T test were used to test mean difference between intervention and control group after checking normality distributions. The result of the final model expressed in terms of adjusted mean difference and 95% CI and statistical significance was declared if the P-value is less than 0.05.
