From the Spearman correlation it can be highlighted that:

• There is a strong correlation (ρ > 0.98) between the different gamma passing rates evaluated (with differing gamma criteria) for each treatment session. • There is a weak correlation (ρ roughly -0.3) between the number of the treatment session and the different gamma passing rates. • There is a week correlation (ρ roughly -0.4) between the number of the treatment session and the relative variation of the volume of the parotids. • There is a week correlation (ρ roughly -0.2,-0.3) between the gamma passing rates and the mean dose variation to the parotids.

Conclusion:
