Indicators of POU product usage for all products.

N is the number of household visits for the 600 treatment and 200 control households across four household visits (not including the baseline). Free chlorine was measured only among self-reported users of chemical products, but N in that column refers to number of households with chemical products at that survey round. Self-reports at surveys in column 1 defined as households that report “At least some water treated” and “last used product” is “today” or “yesterday.” Self-reports at water collection visits in column 2 defined as households that report they “Treat drinking water with [POU Product]” and “how long ago did you treat?” ≤24 hours.
