Expression profile of FRGs in TB. A The GSEA results suggested that ferroptosis is important in the pathogenesis of TB. B Volcano plot of the FRGs (the green dots represented the down-regulated FRGs and red dots represented the up-regulated FRGs). C The correlation plot represented the degree of correlation of the 22 FRGs. D Box plots depicted the differentially expressed FRGs between the HC and TB groups. *p < 0.05, **p < 0.01, ***p < 0.001
