Meningioma of the cerebellopontine angle in identical twins: a case report.
Article in Journal of neuro-oncology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Meningiomas in identical twins are extremely rare. To our knowledge, only one previous report of meningiomas in identical twins has been published. We present identical twin sisters with meningiomas. The tumors were located at a similar, but not a common, position (the cerebellopontine angle) in both twins. Histologically, both tumors were diagnosed as meningothelial meningiomas with an angiomatous component. Immunohistochemically, the Ki-67 indices in the two cases were 1.0 and 1.1, and the p53 positive rates were 0.2 and 0.9. The specimens in both cases were reactive to neurofibromin 2 (NF2). A comparative genomic hybridization (CGH) assay revealed an aberration in the long arm of chromosome X, but no aberrations in the long arm of chromosome 22 in either case. These results strongly suggest that genetic aberrations other than NF2 are associated with tumorigenesis in some types of sporadic meningiomas.
