Development of a Predictive Model of Tuberculosis Transmission among Household Contacts

Figure 5

Decision curve analysis of the predictive model. The dotted line represents the model. Area among the dotted line, the solid line, and the dashed line represents the net benefit from applying this model for prediction of TB transmission in households exposed to TB patients. The decision curve shows that when the threshold probability of a patient is <30%, application of this mode adds more benefit than either the treat-all or the treat-none strategies.
