The adjusted absolute risk difference represents adjusted differences between group-specific changes over time and was estimated with the use of generalized linear model.
The adjusted odds ratios for the interaction between groups (intervention vs. non intervention) and time (before vs after the implementation of the ORI) were estimated with the use of the multivariate generalized estimating-equations extension of logistic regression models.
P < 0.05 were considered to indicate statistical significance.
Subgroup-specific effects were reported when a significant interaction with a subgroup variable was detected. p value of the three-way interaction for level of education*time*intervention was 0.034.
