CI confidence interval, MTA medial temporal atrophy, SD standard deviation
^aThe odds ratios were obtained by multivariate logistic regression with backward stepwise analysis. Gender, MTA, year of education, peritumoral edema, localization were entered into the model but were removed through the stepwise regression process
^bData for 12 cases were excluded since the tumor was not extended to cerebrum (3 intraventricular, 8 skull base, 1 infratentorial)
^cData for 2 were excluded since the tumor was located bilaterally
