Decision curves as a function of RRR
. In this figure, RRRHosp = 0, RRRRx = 2 to 8%, HRx = HHosp = Hte = 0. As the effect of treatment increases, the regret associated with treating all patients and with the SUPPORT model slightly decreases. The strategy of using the SUPPORT model to refer a patient to hospice is the action with the least amount of regret for the wider range of threshold probabilities.
