**Figure 1.** **Genetic variation of m6A regulators in thyroid cancer.** (**A**) The protein-protein interaction (PPI) network of 23 m6A regulators. (**B**) The mutation frequency. (**C**) The location of the change of m6A regulator CNV on chromosome. (**D**) m6A waterfall plot. The right vertical coordinate represents m6A regulators, and the left vertical coordinate represents the mutation rate of m6A regulators in thyroid cancer. (**E**) Pearson correlation analysis shows the correlation of 23 m6A methylation modification regulators in thyroid cancer. (**F**) m6A methylation regulators expression in thyroid cancer. The figure shows the expression of 23 m6A regulators in thyroid cancer tumors and normal specimens. (**G**) The difference of mRNA expression levels of 23 m6A regulators between normal and thyroid cancer samples. The asterisk indicates statistical *p* value (^{*}*P* < 0.05, ^{**} *P* < 0.01, ^{***}*P* < 0.001).
