Figure 2. Decision curves and relative utility curve of the LLP risk model compared with alternative strategies for lung cancer screening decisions.

Figure 2

The smoking duration for relative utility curves involves 4 categories, whereas it had to be restricted to 2 categories for decision curves for technical reasons. DCA = decision curve analysis; EUELC = European Early Lung Cancer; LLP = Liverpool Lung Project; LLPC = Liverpool Lung Project prospective cohort; RU = relative utility.
