a95% CI calculated by bootstrap resampling matched village pairs with 1000 iterations.
bWater treatment was confirmed if the family (i) self-reported treating water in the previous 7 days, (ii) had treated water at the time of the interview and (iii) could produce the materials they used to treat water.
