On the day of admission, the highest levels of CCAT1 (Figure 1A, p < 0.05), IFN‐γ (Figure 1B, p < 0.05), IL‐1β (Figure 1C, p < 0.05), iNOS (Figure 1D, p < 0.05), and TNF‐α (Figure 1E, p < 0.05) were detected in N‐TB patients, followed by R‐TB patients and controls, while the lowest levels of plasma IL‐10 were detected in N‐TB patients, followed by R‐TB patients and controls (Figure 1F, p < 0.05). This evidence concerns the gene TNF and tuberculosis.
