Diagnostic sensitivity and specificity of AFB Smear versus reference standard

TP=true positive, FN=false negative, FP=false positive, TN=true negative

Meta-analysis of the diagnosis of tuberculous mdeningitis in the 11 studies included. Reference standards for each of the studies included some combination of AFB smear, CSF profile, M. tuberculosis culture, NAAT, B symptom evaluation, and/or the Uniform Tuberculous Meningitis Case Definition (Marais criteria). Dashed vertical lines show the pooled estimates. I2 shows inter-study heterogeneity.
