Significant differences in binary variables were tested between intervention baseline and follow-up using χ 2 tests, comparison baseline and follow-up using χ 2 tests, and percentage difference (follow-up – baseline) for intervention and comparison using a Wald test on the interaction term of a logistic regression. 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. Percentage difference may vary slightly from reported percentage follow-up – reported percentage baseline due to rounding.
