Figure 1. Serum expression of miR-145 and its correlation with serum levels of inflammatory cytokines. A. Serum expression of miR-145 was decreased in the TB patients compared with the healthy controls, and the lowest expression of miR-145 was observed in the ATB patients. B and C. Serum expression of miR-145 was negatively correlated with the concentrations of IL-1β (B; r = −0.56, P < 0.001) and TNF-α (C; r = −0.63, P < 0.001). HC, healthy control; LTB, latent tuberculosis; ATB, active tuberculosis; **P < 0.01, ***P < 0.001 vs. HC; ^## P < 0.01 vs. LTB.
