**Figure 6.** **Establishment of the OS nomogram for HCC patients.** (**A**) Nomogram for predicting OS of HCC. There are three components in this nomogram: the four MDEGs score, HCC risk factor and T stage. Each of them generates points according to the line drawn upward. And the total points of the three components of an individual patient lie on "Total Points" axis which corresponds to the probability of 3‐year and 5‐year OS rate plotted on the two axes below. (**B**) Calibration plots of the nomogram for predicting OS rate at 3 year (Left) and 5 years (Right). The predicted and the actual probabilities of OS were plotted on the x‐ and y‐axis, respectively. (**C**) Kaplan‐Meier curves of three risk subgroups stratified by the total points the nomogram gives.
