Effects of water quality, sanitation, handwashing, and nutritional interventions on diarrhoea and child growth in rural Kenya: a cluster-randomised controlled trial

Poor nutrition and exposure to faecal contamination are associated with diarrhoea and growth faltering, both of which have long-term consequences for child health. This trial aimed to assess whether water, sanitation, handwashing, and nutrition interventions reduced diarrhoea or growth faltering.
