Of the 51 NF2 meningiomas, 46 showed loss of Merlin staining, whereas 53 of 58 non‐NF2 meningiomas retained Merlin staining (sensitivity: 90.2% [95% CI: 78.6%–96.7%], specificity: 91.4% [95% CI: 81.0%–97.1%], positive predictive value: 90.2% [95% CI: 78.6%–96.7%], negative predictive value: 91.4% [95% CI: 81.0%–97.1%]). Here, NF2 is linked to meningioma.
