*In the last column, ‘overall findings’ are summarised from evidence as reported in the systematic reviews, qualitative and quantitative findings, and quantitative findings from review of reviews (RoR). Kindly refer to online supplemental appendix 9 for the expanded version of this table.
†Apart from Jain et al,29 30 there were 25 systematic reviews that assessed the effects of more than one intervention that are not part of this table. Of these reviews, the majority (18) were low confidence SRs and the intervention components were heterogenous. We provide a summary of Jain et al29 30 in this table because it is one of the only included SRs that assessed community engagement interventions. Intervention and outcome codes are taken from online supplemental appendix 1.
