Note: The program effect for each outcome variables was estimated using a Mixed Effect model to adjust for the cluster randomization, baseline difference, repeated measurement, and covariates. SD: Standard deviation; CI: Confidence interval; n/a: not applicable. Adjusted diff.: Adjusted differences,

*: p between 0.05–0.01,

**: p between 0.01–0.001, and

***: p < 0.001.
