Table 1 Posterior median, 95% credible interval (CI95), and the deviance information criterion (DIC) for three conditional independent models and one conditional dependent model for the sensitivity (Se), specificity (Sp), and prevalence (prev) of three Mycoplasma bovis antibody ELISA tests (ID screen, Bio K302, Bio K432) on 156 bulk tank milk samples from Belgian (n = 85) and Swiss (n = 71) dairy herds. Manufacturer cutoff values for the sample-to-positive percentage (S/P%) were used. The first independent model (bold) was used for further Bayesian latent class modelling
