FIG. 3.

LPS-induced IL-10 production of pulmonary TB patients was slightly but significantly increased in active TB and normalized at the end of therapy compared to that of the control group. In the longitudinal study, no significant differences were detectable between the mild-to-moderate TB and advanced-TB subgroups (see text; not shown). Each dot in the cross-sectional study represents one individual. A horizontal bar indicates the median of each group. A dashed line indicates the lower detection limit of the assay. A statistically significant difference (P < 0.05) is indicated by the asterisk (Mann-Whitney U test).
