Figure 4:

Decision Curve Analysis demonstrating the net benefit to renal functional preservation associated with the use of the nomogram-derived probability. The model weighs the net benefit (y-axis) of the choice to forgo radical nephrectomy at various threshold probabilities (x-axis) can be observed, based both the full and reduced model, for the prediction of eGFR reduction to ≤ 45. The curves are shown nearly overlapping, highlighting the equal clinical utility of the reduced model relative to the model that includes the patient comorbidity profile.
