Data are % (95% CI), adjusted odds ratio (95% CI), or n (%).
*
Main effect p values are reported if the intervention type by period interaction variable is not significant.
†
The adjusted linear mixed-effects models account for clustering at the hospital level, adjusting for age, sex, and dehydration status of patient.
‡
Frequency of diarrhoea among household contacts is the number of people affected by diarrhoea after discharge divided by the number of people that share the same cooking pot in the household.
§
The cause of mortality was acute myocardial infarction in an adult participant; after review by the Institutional Review Board, the event was determined to not have a causal relationship with the intervention.
