Environmental contamination with Toxocara eggs: a quantitative approach to estimate the relative contributions of dogs, cats and foxes, and to assess the efficacy of advised interventions in dogs

Table 4 Estimated contribution of household dogs under different simulated deworming regimens and compliance rates

The estimated percent contribution (95 % CI) of household dogs to the overall daily Toxocara egg output under different simulated deworming regimens and compliance rates. Baseline compliance refers to the observed compliance rates according to Nijsse et al. [9]
