Decision curve analysis for the predictive model and the validation. The Y-axis measures the net benefit. The dashed line represents the model. The black line represents the assumption that all patients have post-CT-TNB hemoptysis, and the orange line represents the assumption that no patients have post-CT-TNB hemoptysis. The decision curve shows that when the threshold probability of a patient is ≥10% (a) or between 5 and 90% (b), applying this model to predict post-CT-TNB hemoptysis adds more benefit than either the treat-all or the treat-none strategies.
