Univariable linear regression of contralateral parotid gland mean dose (PGdose) predicting parotid gland surface reduction (∆PG-surface) for different weeks (lines) and regression characteristics (Table). Correlation increases over time, but remained weak. Data point represent ∆PG-surface values for week 6.
