Radiomics nomogram, calibration curves and DCA curves. (A) The radiomics nomogram, combining age, BMI, gender and Radscore, was developed in the training cohort. (B–D) The nomogram calibration curves in training (B), internal validation (C), and external validation (D) cohorts. Calibration curves indicate the goodness-of-ft of the model. (E) Decision curve analysis for different models
