- NOTES: Significant differences in continuous variables were tested between intervention baseline and follow-up using independent sample t-tests, comparison baseline and follow-up using independent sample t-tests tests, and mean difference (follow-up – baseline) for intervention and comparison using a F-test on the interaction term of a linear regression (more details can be seen in Additional file 3: Table S3)
- **p < 0.01
- aThe significance of the mean difference was not tested, as this variable was only of interest to calculate percent of dollars spent on fruits and vegetables
