No results are available for the bilateral language LI section of the relative position analysis because all patients with bilateral LI values were excluded.
Low tumor grade = grade I or grade II gliomas; high tumor grade = grade III or grade IV (Glioblastoma) tumors.

For the relative position analysis (tumors ipsi‐ and contralateral to lateralization compared to laterality shift), an additional eight patients were excluded for the presence of bilateral LI values.
