Table 2 Posterior estimates of test specificities and sensitivities to diagnose TBM, for overall population, and stratified by HIV infection. Test specificities are the same for all strata
From: A novel diagnostic model for tuberculous meningitis using Bayesian latent class analysis
| Â | Specificity (%) | Sensitivity (%) | ||
|---|---|---|---|---|

MGIT | 99.7 (98.4—100.0) | 42.1 (33.0—52.7) | 75.9 (65.7—84.2) | 39.1 (29.6—50.4) |
Xpert | 99.9 (99.4—100.0) | 37.2 (28.7—48.3) | 75.5 (64.7—84.3) | 33.8 (24.9—45.7) |
