  1. n: Number of volumes with related plans. Mean values of Volumes (Vol). Standard deviations of the dose distributions σD, dose minima and maxima (Dmin, Dmax), divided by the mean doses (Dmean) within PTVs and PTV shrunk by 5 mm (PTV5) for several groups of plans (CRT: Conformal radiotherapy, IMRT: Intensity modulated radiotherapy; SIB: Simultaneous Integrated Boost). The upper value in each cell is the mean value; the lower value is the corresponding standard deviation
