RL led in conceptualization of the study, drafting protocol, and data collection. RL wrote the first draft of the report with input from MAC, KKG, GOA, MMB, DD, and MH. MAC, KKG, RG, GOA, FA, MC, MH, MJD, IA, AY reviewed the protocol and submitted it for ethical clearance. DD participated in delivery of the intervention and data collection. RL prepared the analysis plan. Prior to seeing the data, MMB modified the analysis plan together with RL to increase the robustness of the analysis. SI then made additional modifications to the analysis plan together with RL. SI subsequently conducted the analysis. RL, GOA, SI, MAC, and KKG interpreted the analysis. All authors made corrections to the manuscript and approved the final document. All authors had full access to all the data in the study and have full responsibility for the decision to submit for publication. RL and DD have verified the data.
