Description of patients and samples used in the study. The group column shows which patient sample sets were used in the training or validation cohort. The total dose column shows the doses (given in 2 Gy fractions over five days per week) received by the patients after which miRNA expression could (green colour) or could not (no colour) be measured. Sampling was performed on the day when an accumulated dose of 2, 10, and 20 Gy, and one (1) month after the full dose of 46 or 50 Gy, was reached.
