The qRT‒PCR results showed that the mRNA expression of METTL3, YTHDC1, RBM15B, LRPPRC and CBLL1 in osteomyelitis tissues was significantly increased, while that of YTHDF2 was significantly decreased (p < 0.05), which was consistent with the results of bioinformatics analysis (Figures 10A–F). Here, YTHDF2 is linked to osteomyelitis.
