Review in HNO, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 1 of them a synthesis that pooled it.

1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Schwannomas are benign Schwann cell-derived tumors of the peripheral nerve sheath often involving the vestibular cranial nerve (vestibular schwannoma). Histologically, they consist of bipolar spindle cells and show a moderate cellularity. Typically, Antoni A regions with a storiform pattern and loose Antoni B regions are intermingled. Verocay bodies are the pathognomonic palisading structures. Malignant transformation is rare. Merlin (schwannomin), the protein product of NF2, is inactivated by mutations, loss of heterozygosity or methylation. Within neurofibromatosis type 2, a germline mutation is present in about half of cases, whereas tumors demonstrate an additional second hit of the NF2 gene. A loss of chromosome 22 or 22q is common. Merlin links the cell membrane with the cytoskeleton and regulates intracellular signaling pathways leading to dysorganization when merlin is inactivated. Loss of merlin activates Rac1 and Ras, and the PAK1, mTORC1, EGFR-Ras-ERK, PI3K-Akt, WNT and Hippo pathways as well as receptor tyrosine kinases. Furthermore, merlin locates to the nucleus and inhibits E3 ubiquitin ligase CRL4
