We found that the prognosis of the meningiomas was not different location-wise (5-year PFS: 82.1% in “Supratentorial” vs 86.7% in “Infratentorial”, p = 0.18) (Table 2, Fig. 1B) but was different mutation-wise (5-year PFS: 77.9% in NF2 vs. 90.3% in non-NF2, p = 0.04 (Table 2, Fig. 1C). Here, NF2 is linked to meningioma.
