Flow chart of the data analysis process. The GSE83456 dataset was used to find FRGs associated with TB. The core FRGs were identified using WGCNA, and validated using the GSE42826, GSE28623, GSE34608 datasets and qRT-PCR analysis. Two subtypes related to ferroptosis were then created based on the ferroptosis score. Differential expression analysis, GSEA, and immune cell infiltration analysis were performed between the two subtypes
