^aThe study included 18 villages in Central, 20 in Upper West, and 20 in Volta, split evenly between interventions in each region. Percentages account for unequal selection probability and nonresponse rates. ICC = 0.349 for ownership of a usable latrine at the village level in the full sample. P-values were generated with a t test.

^bPrivate latrine ownership is different from use in Figure 3, as use includes families renting houses with latrines.

^cBased on respondent recall of the age of their latrine at the follow-up survey.
