2.2. Portraying the Landscape of m6A RNA Methylation Regulator Expression

The expression levels of six m⁶A RNA methylation regulators between tumor and normal tissues were compared using the t-test. The expression pattern of m⁶A RNA methylation regulators in COAD samples was denoted by the Pearson correlation matrix, and a correlation coefficient (r) was calculated. We plotted the ROC curve and calculated the area under the curve (AUC) to estimate the discrimination ability. The m⁶A RNA methylation regulators and clinicopathological features were analyzed using the t-test or one-way ANOVA.
