The nomogram and its performance. The nomogram, calibration curve, and ROC based on the joint model (rad-score and edge) were drawn (a–c). b The horizontal axis of the calibration curve is the predicted incidence of the acinar-papillary pattern, and the vertical axis is the observed incidence. The red diagonal line is the reference line, indicating that the predicted value equals to the observed value. The black line is the calibration curve, and the yellow areas on both sides represent 95% CI. c The ROC curve and 95% confidence interval of the joint model were drawn by the Bootstrap resampling (times = 500). Rad-score, radiomics signature score
