WHO, World Health Organization.
aAQ was calculated according to the method in Western Aphasia Battery (Kertesz and Poole, 1974), AQ = (S+R/10+N/10+C/23)*2.
bA score of 93.8 is usually treated as the cut‐off between aphasia and non‐aphasia.
cNew or increased postoperative language deficits, e.g., aphasia, anomia.
