Receiver operating characteristics-curve (ROC) of the prediction of the appearance of a pneumothorax in multivariate logistic regression analysis, clinical model (beige), texture model (green) and combined model (blue). The combined mode achieved an AUC of 0.78 [95%CI: 0.70–0.86], the clinical model achieved an AUC of 0.73 [95% CI: 0.65–0.81], while the texture model an AUC of 0.64 [95% CI: 0.54–0.73]
