Figure 1
Flow chart of patients recruited to the study.
1Referral based on cough >2weeks, FTT, history of contact with a TB case and a TST ≥10 mm at study closure 2Abnormal CXR; MTB positive by the Hain MTB test or Roche test. 3Abnormal CXR; culture negative for MTB. 4Normal CXR; culture positive for NTM and 5Normal CXR; culture negative for MTB and NTM. Abbreviations: FTT – failure to thrive; CVW- case verification ward; CXR – chest X-ray; TST - tuberculin skin test; QFTGIT – QuantiFERON Gold In-tube test; dcRT-MLPA – dual colour reverse transcriptase – multiplex ligation dependent probe amplification; MTB – Mycobacterium tuberculosis; NTM – non-tuberculous mycobacteria.
