Fig. 1From: A novel diagnostic model for tuberculous meningitis using Bayesian latent class analysisBasic model design. Unknown TBM status is linked with test results. The probability of a positive test depends on bacillary burden, which in turn depends on modulating factors. TBM risk factors help determining an individual’s TBM status. The distribution of test results shown on the bar plots are for demonstration only and do not correspond to the actual numbersBack to article page
