Constructed multiparametric radiomics nomogram and calibration curves. a The developed radiomic nomogram for differentiating POC and SOC. b–c Calibration curves for differentiating POC and SOC in the training and validation cohort, respectively. The calibration curve illustrates the calibration of the nomogram in terms of the agreement between the predicted risk of SOC and the observed outcomes. The diagonal dotted line represents a perfect prediction, and the dotted line represents the predictive performance of the nomogram. Closer fit to the diagonal dotted line indicates a better prediction
