Incidental finding of subgemmal neurogenous plaque upon retrospective evaluation of oral lymphoepithelial cysts.
Article in Oral and maxillofacial surgery, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeWe aimed to compare the histomorphological features of oral lymphoepithelial cysts (OLC) in different locations of the oral cavity and to verify the association between oral lymphoepithelial cysts and subgemmal neurogenous plaque (SNP) on biopsies from the lateral border of the tongue.
methodsAll cases diagnosed as OLC from the Oral Pathology Service at the School of Dentistry/University of São Paulo were retrieved. For all the cysts located in the tongue, their association to SNP was analyzed. Immunohistochemical staining against S100 was performed to confirm the diagnosis of SNP.
resultsThirty-one cases were selected for morphological analysis and SNP was identified in 40% of cases, all of them positive for S100. In these cases, macroscopic analysis demonstrated two independent fragments. Microscopic analysis showed that cysts located in the floor of the mouth and ventral surface of the tongue showed less intense exocytosis, less formation of lymphoid follicles, and predominantly a moderate inflammatory infiltrate.
conclusionsOLC have a similar histological pattern regardless the location within the oral cavity and. In some cases, the biopsy specimen may be accompanied by a SNP as an adjacent independent structure.
