DVH values from the External Beam plans: Upper part: Volume of the PTV45 receiving 95% of the planning aim dose for the separate centres in % for the first (A) and the second (B) External Beam Planning workshop. Lower part, the minimum dose to the ITV45 in Gy for the first (C) and the second (D) workshop. Horizontal (red) lines: hard constraints. For A and B the soft constraint is that the values should be close to 95%. Note that not all centres submitted plans for two workshops, and that some centres reported erroneous values. The encircled centres submitted evaluable plans for the two workshops.
