A Two week prevalence of household diarrhea

B The final model was not adjusted for other covariates

C The full multivariate models were adjusted for tambos (a proxy for living in a flood prone region), number of individuals in the household, and education level of the head of household (a proxy for socioeconomic status of the household)

D Household latrine

E Within household that had a latrine, did that latrine overflow (1 or more times) in the past year.
