TB Infection and TB Disease Prevalence in Child HHCs Overall and by 5 Year Age Groupings*

Abbreviations: HHC, household contact; IGRA, interferon gamma release assay; TB, tuberculosis

*TB infection is based on interferon gamma release assay using QuantiFERON TB Gold or QuantiFERON Gold In-Tube. TB disease was adjudicated by a study outcomes review group. Panel A TB infection includes N=279 HHCs age <15 years with determinate IGRA results, Panel B N=303 HHCs age <15 years, and Panel C N=160 HHCs age <15 years with IGRA-positive results. Proportions were estimated by logistic regression using generalized estimating equations and confidence intervals are based on robust standard error. The vertical bars are 95% confidence intervals.
