Table 2 Summary of the organ doses (mean ± standard deviation) of the KBRT and expert plans. All doses are normalized to dose that is prescribed to the target volume. The Wilcoxon test shows significantly lower bladder dose for the KBRT plans (at D30), as well as lower rectal dose (at D10 and D30) for the expert plans
