Figure 5

Decision curves of models. The horizontal axis represents the predicted risk range, ranging from 0.0 to 1.0, and the ordinate represents the net clinical benefit, calculated by summing the benefits (true-positive results) and subtracting the harms (false-positive results). The gray line is the net benefit of assuming that all patients were in the aggravation group; the black line is the net benefit of assuming no patients aggravated; the pink, green and red lines are the expected net benefit based on clinical, radiomics and combined model respectively, with the combined model (red line) showing the highest net benefit.
