Mean DSC, ASD and MSD in group A for automatic (AUTO) and corrected (CORR) volumes, both compared to manual (MAN) segmentation. Vertical black line separates OAR section from CTV, and CTV from global mean (TOTAL). Last column of each section refers to mean values ("subtotal") for OAR and CTV. SC data were excluded since no correction was necessary. RP: retropharyngeal; RST: retrostyloid; RCL: retroclavicular.
