Decision curve analysis (DCA) for the radiomics nomogram model (blue line) and conventional MRI evaluation model (red line). The gray line represents the assumption that all patients are diagnosed with DON. The black line represents the assumption that no patient is diagnosed with DON. The decision curve analysis (DCA) shows that the radiomics nomogram is more advantageous than is the conventional MRI evaluation. Convention, conventional MRI evaluation model; nomogram, radiomics nomogram
