Table 1.

Pearson correlation coefficients and Wilcoxon rank sum test p-values for the difference in dose-volume statistics between the auto-segmented and manually delineated OARs for each patient group. Statistically significant differences (p < 0.05) are written in bold and marked with an *. D₂ corresponds to the dose that the OAR receives on 2 % of its volume and V₂₀ and V₅ correspond to the percentage volume of the organ receiving at least 20 Gy and 5 Gy, respectively. D_mean corresponds to the mean dose.
