Decision curve analysis (DCA) of the radiomics model, clinics model and nomogram model. The X-axis is the threshold probability. The y-axis represents the net benefit, which is calculated by the difference between the expected benefit and the expected harm associated with the decision. The higher curve at a range threshold probability is the optimal prediction to maximize the net benefit. The decision curve shows that the nomogram model provides more net benefit than the other two models
