- *Chi-square test, ** Wilcoxon test
- Table shows that before the intervention two groups were homogenous based on BSE performance over a period of 4 months. However, after the intervention, the largest number of BSEs was four times among 60% of the participants in the intervention group and once among 24% of the participants in the control group during four months
