Decision curve analyses for the radiomics-clinical model compared with the radiomics model and clinical model in training cohort (A) and the testing cohort (B). The decision curve analysis presents that the net benefits of the combined model for the prediction of IMA were higher than the clinical model and radiomics model. Model 1 was the radiomics model, model 2 was the clinical model, and model 3 was the combined model. The decision curve analysis (DCA) showed that the line of the combined model was higher than the clinical model and the radiomics model when the probability ranged from 0 to 1.
