Croke 2022.

Methods	Cluster‐randomised trial assessing the effect of a national water, sanitation, and hygiene program on adherence with COVID‐19 policies in Congo. The trial is a follow‐up of the Villages et Ecoles Assainis programme which was running prior to the COVID‐19 pandemic.
Participants	332 communities were randomly assigned to the Villages et Ecoles Assainis program or control. (590/1312; 45%) individuals who owned phones were surveyed by phone 3 times between May 2020 to August 2021.
Interventions	Large‐scale water and sanitation programme not described in detail.
Outcomes	Primary outcomes were COVID symptoms, non‐ COVID illness symptoms, child health, psychological well‐being, and vaccine acceptance.  Secondary outcomes included COVID‐19 preventive behaviour and knowledge, and perceptions of governmental performance, including COVID response. All outcomes were self‐reported.  COVID symptoms were defined as the number of household members in the past week with fever, dry cough, difficulty breathing/shortness of breath, or fatigue, while non‐COVID illness variable was defined as the number of sick household members in the last 7 days (excluding those with COVID symptoms). The child health index was created using the proportion of children under 5 with fever/cough/diarrhoea in the last 2 weeks. The mental health index is a summary index of scores from answers to questions.
Notes	Cannot find NCT and unclear funders although acknowledgments list a potential load of funders. Probably public.
