A radar plot of the performance (represented as sensitivity values 0–100%) of Xpert MTB/RIF compared to liquid culture for various specimen types. PTB-pulmonary tuberculosis, BAL-bronchoalveolar lavage, EPTB, CSF-cerebrospinal fluid and TBM-tuberculosis meningitis. The solid radial arms illustrate sensitivity (%) of overall pooled data, and the dashed radial arms report studies among HIV/TB co-infected individuals.

Children Overall PTB (sputum): n=12 studies, Smear Positive PTB: n=6 studies, Smear Negative PTB: n=7 studies, Overall Gastic Lavage: n=7 studies [37]. EPTB Overall EPTB: n=36 studies [38]; Lymph Node Tissue/Aspirate: n=18 studies [39], n= 1 HIV positive cohort [40]; CFS(TBM): n=18 studies [39], n=1 HIV positive cohort, mixed CSF samples [41], n=1 HIV positive cohort, centrifuged CSF [42]; Pleural fluid: n=24 studies [43], n=1 high TB-HIV prevalence cohort [44]; Urine: n=1 hospitalised, HIV positive cohort [45].
