Figure 6

Decision curve analysis for the 5-year survival predictions. In the decision curve analysis, the -axis indicates net beneft, calculated by summing the benefts (true positives) and subtracting the harms (false positives). The nomogram model (red dotted line) had the highest net benefit compared with the pTNM staging system (green dotted line). The straight line represents the assumption that all the patients will die, and the horizontal line represents the assumption that none of the patients will die.
