Fig. 4.
Normalized gene expression values for DDB2, IL1B, and TGFB1 gene expression in IMRT patients, interpolated for radiation doses 7.25 Gy and 36.25 Gy. Data are shown as individual datapoints together with the mean ± SD. Significant p-values for the Tukey honest significant difference (HSD) test: asterisk for p < 0.05 and double asterisk for p < 0.01; hash indicates a very large effect size (|d| ≥ 1.2). All comparisons found significant by the Tukey HSD test also show large or very large effect size, which are not shown on the graph for reasons of clarity
