The results of ssGSEA analysis revealed that a total of 7 immune cells were significantly different in two m6A subtypes, among which activated B cells, activated CD8 T cells, CD56 bright natural killer cells, and eosinophils were highly abundant in cluster A osteomyelitis, while activated dendritic cells, natural killer cells, and type 2 T helper cells were highly abundant in cluster B osteomyelitis (Figure 4A). Here, CD8A is linked to osteomyelitis.
