Development and Validation of a Prediction Pneumothorax Model in CT-Guided Transthoracic Needle Biopsy for Solitary Pulmonary Nodule

Figure 5

Decision curve analysis for the predictive model and the validation. The y-axis measures the net benefit. The dotted line represents the model. The black line represents the assumption that all patients have pneumothorax post-CT-TNB. Thin orange line represents the assumption that no patients have pneumothorax post-CT-TNB. The decision curve shows that if the threshold probability of an individual is < 55%, using this model to predict pneumothorax post-CT-TNB adds more benefit than either the treat-all tactics or the treat-none tactics.
