Data presented are mean± SD or n (%).

^aP values in paired t-test (for continuous variables) or paired Chi-square test (for dichotomous variables) for differences between the baseline and post-intervention.

^bP values in ANOVA (for continuous variables) or Chi-square (for dichotomous variables) test for differences among the three groups at the baseline survey.

^cP value in ANOVA (for continuous variables) or Chi-square (for dichotomous variables) test for differences among the three groups after the intervention.
