Estimated combined effect sizes with confidence limits for each intervention type. Random effects models. Studies may be classified as implementing more than one type of intervention. Entire group comparisons for primary outcomes.

aConfidence intervals only approximate because cluster randomization is not taken into account.

bModel includes outcome months.

cControl groups do not include strategies of the same intervention type.
