All dose values are in Gray (Gy) or Cobalt60 Gray Equivalent (CGE) = 1.1 × Gy and the PMRR’s in Gy−1 or CGE−1. MLD = mean lung dose. MLD ratio = MLD upper lobes/MLD lower lobes. SUV0-10 = mean SUV in region of lung receiving 0 to 10 Gy or CGE, SUV10-20 = 10 to 20 Gy or CGE, SUV20-30 = 20 to 30 Gy or CGE, SUV30-40 = 30 to 40 Gy or CGE, SUV40-50 = 40 to 50 Gy or CGE p value is for logistic regression.
