Figure 1. Proportion of positive Tuberculin Skin Tests (TST) and Quantiferon Gold In Tube Tests (QFT), stratified by age and mother's HIV status.

Figure 1

A. Proportion of positive TST and QFTs among children ≤60 months, stratified by age-category. There is a negative trend in TST positivity with increasing age, chi-square test for trend p=0.014. The trend of QFT positivity and age was not statistically significant, chi-square test for trend p=0.576. B. Proportion of positive QFTs, stratified by a HIV-status of mother. Children had a higher proportion of positive QFTs for all age-categories, though this was not statistically significant for any age-categories. C. Proportion of positive TSTs, stratified by age and mother's HIV-status. Children born to HIV-infected mothers had a higher prevalence of TST positivity in the 24-35 month age-category (p=0.013) and the 36-60 month age group (p=0.001) compared to the children born to HIV-uninfected mothers in the same age-group. A positive TST is defined as induration ≥10mm.
