Pairwise comparisons of OARs doses. Each data point was derived from subtracting the value achieved with one plan from the one achieved with another plan. Horizontal bars indicate median values. OARs = organs at risk; TPBT = trachea and proximal bronchial tree; MLD = mean lung dose; ESO = esophagus; GV = great vessels; SC = spinal cord; Dmax = maximum dose; D1cc = minimum absorbed dose that covers 1 cc of the volume; D2cc = minimum absorbed dose that covers 2 cc of the volume; VD = volume that receives at least the absorbed dose D Gy; HO, MHE, and HE plans = homogeneous, moderate heterogeneous, and heterogeneous plans. *percentage
