Overall volume and positional change of the parotid glands. Volumetric change of the parotid glands (PGs) (a) and distance change between the PGs in medio-lateral direction (b) from the start of treatment. The black line corresponds to the average of the chemoradiotherapy (CRT) group, the grey line corresponds to the average of the radiotherapy alone (RT) group. RT starts at treatment day 1. Saline solution was administered during the first, second and third chemotherapy cycle, respectively during the first, fourth and seventh week of treatment (arrows). Most patients in the RT alone group received RT with an accelerated scheme, therefore the grey line stops at week 6
