CI, confidence interval. Group (intervention vs. control) and time (6-mo vs. BL and 12 mo vs. BL) effects and group-by-time interactions were modelled using generalized linear mixed models. No results from the control group, while they did not answer the questionnaire at the six-month follow-up point.
