Outcome Measures

Primary Outcomes (1)

  • IGRA status per site

    Proportion of participants with a positive IGRA, per site, calculated using per protocol population. 95% CI will summarize the precision associated with the estimate.

    Screening

Secondary Outcomes (3)

  • IGRA status by age group per site

    Screening

  • Suspected pulmonary TB during follow-up period

    Day 1 up to 30 months

  • Laboratory-confirmed pulmonary TB during follow-up period

    Day 1 up to 30 months
