Identification of hub genes in TB. A PPI network of the DEGs in the STRING database. Each node represents a protein, and the spiral structure inside the node represents the known three-dimensional structure of the protein. The color of the node represents the score value of the interaction. The lines between nodes represent the interactions between two proteins, and different colors correspond to different interaction types. B Upset plot of the hub genes identified using the five algorithms. The x-axis represents the five algorithms, and the y-axis represents the number of genes commonly identified by the five algorithms
