TST: tuberculin skin test (Mantoux test); IGRA: interferon-γ release assay; M. tuberculosis: Mycobacterium tuberculosis; TB: tuberculosis; NNS: number needed to screen; na: not applicable. #: The discrepancy between nine known IGRA results and 21 positive TST results can be due to referral or transfer-out, bacteriological results known before IGRA was planned, or no IGRA performed in BCG-vaccinated asymptomatic children with marginal TST results but chest radiograph repeated after 4–6 weeks.
