Subarachnoid epithelial cyst of the cerebellum. Immunohistochemical and ultrastructural studies.
Article in Acta neuropathologica, 1989. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
This report describes the immunohistochemical and ultrastructural studies of a subarachnoid epithelial cyst of the cerebellum found incidentally at autopsy of a 76-year-old man. The cyst was composed of an inner epithelial layer, a middle connective tissue layer and an outer arachnoid membrane. The epithelial layer was strongly positive for cytokeratin, carcinoembryonic antigen and epithelial membrane antigen, but negative for glial fibrillary acidic protein, S-100 protein, neuron-specific enolase and vimentin. Ultrastructurally, the epithelial layer had four distinct types of cells: ciliated cells, non-ciliated cells with coated microvilli, basal cells with tonofilaments and desmosomes, and cells with dense-core secretory granules (Kulchitsky cells). The latter two types of cells have not been described previously in epithelial cysts of the CNS. The lining epithelium closely resembled the upper respiratory epithelium. The findings suggest that the cyst was of endodermal rather than neuroectodermal origin.
