- NOTES: Significant differences were tested between intervention baseline and follow-up using chi-squared tests, comparison baseline and follow-up using chi-squared tests, and percent difference (follow-up – baseline) for intervention and comparison using a Wald test on the interaction term of a logistic regression (more details can be seen in Additional file 1: Table S1). This Wald test can be thought of as testing whether the relative change (on an odds ratio scale) is the same in the intervention and comparison groups
