Development of a Predictive Model of Tuberculosis Transmission among Household Contacts

Figure 4

Calibration curves of the predictive model. It shows the degree of consistency between the predicted risks of TB transmission in households exposed to TB patients and observed outcomes. The shadow line represents a perfect prediction by an ideal model, and the dotted line shows the performance of the model. The Hosmer–Lemeshow test yielded a value of 0.754, Emax of 0.078, and Eavg of 0.004. E, difference in predicted and calibrated probabilities between calibration and area under the curve.
