Receiver operating characteristics-curve (ROC) of the prediction of the necessity of a chest tube in the patient subgroup of appearance of any pneumothorax, clinical model (beige), texture model (green), combined model (blue). The combined model achieved an AUC of 0.70 [95% CI: 0.60–0.79], the clinical model achieved an AUC of 0.65 [95% CI: 0.55–0.75], while the texture model achieved an AUC of 0.66 [95% CI: 0.56–0.76]
