  2. 1Summarized as whether anyone in the household experienced diarrhea within the previous 2 weeks
  3. 2Summarized as household being visited within 60 days of baseline intervention and whether anyone in the household experienced diarrhea within the previous 2 weeks
  4. 3Summarized as household being visited after 60 days of baseline intervention and whether anyone in the household experienced diarrhea within the previous 2 weeks
  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
