Figure 4. Relationship between IDO and tuberculin test results.

Figure 4

(A) The IDO MFI was higher for positive TST results than for negative TST results (*P<0.05). (B) The Kyn/Trp ratio did not differ significantly between negative and positive TST results. (C) The diameter of the TST induration was negatively correlated with the IDO MFI (rs -0.297, P=0.045). (D) The TST induration was not correlated with the Kyn/Trp ratio (rs -0.248, P=0.096). MFI: median fluorescence index; PBMCs: peripheral blood mononuclear cells; TST: tuberculin skin test.
