  1. Group represents the effect of treatment condition on the primary and secondary outcomes, Time represents the effect of time on the changes in estimates during the follow-up period regardless of treatment condition. Finally, Group x Time is the interaction effect of group over time, i.e. indicating if the change in estimated results differs significantly over time between the two treatment conditions
