Prevalence, sensitivities and specificities, positive and negative predictive values (PPV's and NPV's) using culture as gold standard and for two Bayesian latent class models.

Model 0 assumed that for a given patient, each diagnostic test was not correlated. The final model (Model 3) assumed that in infected patients, all serological tests were correlated.
*Values shown are mean estimates with 95% confidence interval.
†Values shown are median estimates with 95% credible interval.
‡Prevalence estimated by the models are for the test population as a whole, since they cannot determine whether a given patient was infected or not infected.
