Decision curve analysis (DCA) of the APRI-based nomogram and other predictors for overall survival (OS) in the training cohort (A) and validation cohort (B). The x-axis and the y-axis represent threshold predicted probability and net benefit, respectively. Solid black line: absence of patients experiencing the event. Solid gray line: all patients will die. Each predictor had a line with a corresponding color. The blue bar within the red horizontal line indicated that the nomogram was not the optimal model in this section. Generally, the APRI-based nomogram showed more net benefit with a wider range of threshold probabilities than other predictors.

Abbreviation: APRI, aspartate aminotransferase-to-platelet ratio index.
