^*Shown are prevalence ratios (PRs) and 95% confidence intervals (CIs) for diarrhea for comparisons of households with shared toilet facilities with households with facilities that are not shared. Data were obtained from 51 Demographic and Health Surveys during 2001–2011.

^†Adjusted for type of facility (flush toilet, improved latrine, unimproved latrine) mother's age, mother's educational attainment, highest level of education in the households, and asset ownership.
