Example stratification of LR based on the median peritumour density for the lowest and highest third of dose SD (discarding uninformative middle values). For low dose SD (assumed adequate MDE coverage), peritumour density no longer stratifies patients for LR – suggesting that peritumour density is a potential predictor for MDE. (A) Shows the survival plots on the training data, and (B) shows the validation data.
