To further reveal the relationship between m6A subtypes and the development of osteomyelitis, we found that between the two m6A subtypes from the test group, the expression of 3 collagen-related genes was significantly different, with COL4A1, COL8A2 and COL18A1 both highly expressed in cluster A osteomyelitis. Here, COL4A1 is linked to osteomyelitis.
