Decision curve analysis of the radiomics and clinicopathologic nomogram in the entire cohort (n = 544). The y-axis represents the net benefit, and the x-axis represents the threshold probability. The black line represents the assumption that no patients exhibited long-term overall survival (OS). The grey line represents the assumption that all patients exhibited long-term OS. The decision curves indicated that the radiomics nomogram (red line) showed better clinical utility than the clinicopathologic nomogram (blue line)
