  1. *p < 0.05; **p < 0.01; ***p < 0.001
  2. 1Summarized as whether anyone in the household experienced diarrhea within the previous 2 weeks so that it caused them to miss work (adults) or school (school-aged child)
  3. 2Summarized as whether any adult in the household experienced diarrhea within the previous 2 weeks severe enough to miss work
  4. 3Summarized as whether any children in the household experienced diarrhea within the previous 2 weeks severe enough to miss school
  5. 4Adjusted for all variables in Table 1 plus an indicator variable for whether the water source changed, an indicator variable for whether the person answering the survey questions changed, and a variable indicating any change in the number of adults in the household.
  6. 5 Infinite odds ratios because the prevalence was 0.0% at follow-up
