Fig 4. Relative errors of porcine seroincidence during validation of CystiAgent against result from the Ring Strategy Trial, by intervention type–ring treatment (n = 6 villages), ring screening (n = 8 villages), and mass treatment (n = 7 villages).

Each time point represents the 4-month cumulative seroincidence across the 24-month trial period, as measured by enzyme-linked immune-electro transfer blot (EITB) in pigs. Error bars show inter-quartile range for relative errors among village in each intervention. Within each intervention type, villages with and without pig treatment are combined.
