Paired analysis of the IFN-γ+ SFCs of the 18 participants with tuberculosis were marginal different (ESAT-6 p = 0.0442, Fig. 2C; CFP-10 p = 0.0395, Fig. 2D), without any consequence for clinical practice, as all tuberculosis cases would have been detected by either one of the antigens in both tests. Here, IFNG is linked to tuberculosis.
