Furthermore, pairwise comparisons showed that Ag-TB levels of IL-17A and GM-CSF, together with the PHA levels of TNF-α and IL-13, were higher in children with Mediastinal TB than in those with PTB (p = 0.009 and 0.042, p = 0.025 and p = 0.050, respectively). This evidence concerns the gene CSF2 and tuberculosis.
