Fig 3 — Ascites lymphocytes were in vitro cultured overnight in the absence (medium) or the presence of PPD, HBHA or ESAT-6, and the percentages of IFN-γ-containing CD4⁺ and CD8⁺ T lymphocytes were analyzed by flow cytometry. The values shown are obtained by subtracting the values obtained in the absence of antigen stimulation from those obtained in response to mycobacterial antigens. Filled circles represent values from patients suffering from TB, whereas open circles represent values from non-TB patients. r: Spearman coefficient of correlation.
