Comparison between planned and accumulated dose for the target volumes and organs at risk. Statistical significance was tested by matched-pairs t-tests in case of normally distributed parameters. In case of non-normally distributed parameters Wilcoxon matched-pairs signed rank tests (*) were applied instead. Statistical significance was declared in case of a two-sided p < 0.05. Stated values indicate mean ± standard deviation
