Cox regression model results in TCGA. (A) The survival curves for the m6A risk score in the training set. Grouping was based on the median m6A risk score in the training set. Red is the high-level group, and blue is the low-level group. (B) The survival curves for the m6A risk score in the test set. Red is the high-level group, and blue is the low-level group. Grouping was based on the median m6A risk score in the training set. (C) A forest plot of the multivariate Cox regression model. Hazard ratio is provided in the figure. ** p < 0.01, *** p < 0.001. (D) Patient survival status in the training set. The x-axis is the patient ranking in ascending order by m6A risk score; the y-axis is survival time. The red dots are the dead patients, and the green dots are the surviving patients. (E) Patient survival status in the test set. The x-axis is the patient ranking in ascending order by m6A risk score; the y-axis is survival time. The red dots are the dead patients, and the green dots are the surviving patients.
