Figure 4(b).

Static $D_{\text{eff}}$ of the Reference Plan versus the blurred $D_{\text{eff}}$ of the Reference Plan (left) and the Escalated Plan (right) for $n=0.24$. The blurred $D_{\text{eff}}$, due to geometric uncertainty associated in treatment, is shown as a median value and the 95% confidence limits. The dashed line shows equal static $D_{\text{eff}}$ and blurred $D_{\text{eff}}$ as a reference.
