Table 6. Number of studies (n = 94) that investigated STH species and WASH domains.

Each cell indicates the number of reviewed studies that investigated both an STH species (or any STH) and WASH domains. Higher numbers suggest that certain WASH-STH relationships are more commonly explored in the literature.
