Sensitivity analysis of mortality from treatment for illness X. This graph represents a 1-way sensitivity analysis of
mortality associated with treatment. As mortality from treatment increases from 0-1 on the x-axis, the expected value for
radiation therapy decreases.The threshold mortality at which radiation therapy and no treatment yield equivalent expected
outcomes is 0.125. At mortality risks below this threshold value, radiation therapy is superior to no treatment; at risks
above 0.125,no treatment is the preferred strategy.Tree constructed with TreeAgePro (Williamstown,MA).(Color version
