Decreased (β) coefficients refer to increased child wasting and vice-versa. Child age changes (cmonths)=child age in months divided by child age in the logarithmic scale; cmonths was used to account and adjust for child age changes during the study period.
*PSNP participation and protected drinking water access (cat) is a categorical variable generated from two dichotomous variables (PSNP participation and protected drinking water access).
†Households who neither had protected drinking water access nor participated in PSNP.
‡Households who participated in PSNP, but did not have protected drinking water access.
§Households who had protected drinking water access, but did not participate in PSNP.
¶Households who had protected drinking water access and also participated in PSNP.
