Multivariate analysis (Table III) revealed that among the aforementioned parameters, the recurrence interval and Simpson grade V were independent factors associated with neurological improvement during follow-up with P<0.05 and P=0.049, respectively, and the combination of the WHO grade III, histology (anaplastic or atypical), MIB-1 LI >3, and Simpson grade I parameters can predict the meningioma recurrence. Here, MIB1 is linked to meningioma.
