Methods	Design: cluster‐randomized controlled trial Unit of randomization: village
Participants	Children aged < 5 years of age and caregivers in households located in the trial catchment area that had ≥ 1 child under 5 years of age. In households with > 1 child, the youngest child was recruited. Following the baseline, children were not excluded from subsequent surveys if they had their 5th birthday before the surveys were implemented.
Interventions	Intervention Training lay health workers (CHVs) to provide household visits 2 per month to all households in their catchment and to provide key messages on disease prevention and healthy behaviours during household visits; identify children with diarrhoea and treat them with ORS; identify febrile children and test them for malaria using an RDT and refer RDT‐positive children to health facilities for treatment Based on this intervention the study would not meet inclusion criteria for this review due to "wrong intervention" (only CHVs only treated diarrhoea); however, we will assess for inclusion at the next update of this review. Comparison Usual facility services
Outcomes	Primary outcomes 14‐day prevalence of diarrhoea at 6 months and 12 months among children aged < 5 years 14‐day prevalence of malaria among at 6 months and 12 months among children aged < 5 years Secondary outcomes Coverage of diarrhoea treatment (oral rehydration therapy) among children aged < 5 years with diarrhoea Coverage of RDT for malaria among children aged < 5 years with fever Coverage of family planning practices of caregivers Based on the above outcomes the study would not meet the inclusion criteria for this review; however, we will assess for inclusion at the next update of this review.
Notes	Objective: to assess the effect of a CHV intervention on reducing diarrhoea and fever prevalence in children aged < 5 years, and the participants were followed up at 6 months and 12 months after the intervention started. Associations of CHVs' home visit coverage and intensity with the primary outcomes, 14‐day diarrhoea and fever prevalence, were also examined. Location: 40 communities (20 intervention communities, 20 control communities) in the Volta region, Ghana.
