Fig. 2.

Baseline comparison of interferon-γ responses between BU⁺-HIV⁺ co-infected patients versus BU⁺HIV⁻ patients. Box-and-whisker plots shows interferon-γ (pg/mL) responses of BU⁺HIV⁺ compared to BU⁺HIV⁻ patients at baseline. The box-and-whisker plots were constructed as medians, minimum and maximum values and interquartile ranges. The middle horizontal line represents the median distribution while the lower and upper ends of the box denotes the 25th and 75th percentile of interferon-γ (pg/mL) responses respectively
