As depicted in Figures 1A–D, the gene expression levels of METTL3 and YTHDF1 in the peripheral blood of CHD patients were significantly higher than those in the control group (p < 0.05), whereas the levels of YTHDF2 and YTHDF3 did not differ significantly (p > 0.05). The gene discussed is YTHDF1; the disease is coronary artery disorder.
