Fig 1.
The overall methodological quality of all included studies for tuberculosis detection versus (A) culture reference standard, and (B) CRS.
Fig 2.
The SROC plot of Xpert MTB/RIF’s sensitivity, specificity and AUC (area under the curve) for tuberculosis detection versus (A) culture and (B) CRS. The sensitivity and specificity of one study were represented as a point; the summary sensitivity and specificity was represented as a summary point.
Fig 3.
The SROC plot of Xpert MTB/RIF’s sensitivity, specificity and AUC (area under the curve) for tuberculosis detection in different prevalence regions versus culture reference standard.
(A) High TB burden regions, (B) Middle and low prevalence regions. The sensitivity and specificity of one study were represented as a point; the summary sensitivity and specificity was represented as a summary point.
