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
Aim: Role of mast cells in the development of oral lichen planus (OLP) and oral lichenoid reactions (OLR). Material and Methods: The tissue slices used in this investigation were obtained from the archives of the Department of Oral Pathology and were formalin-fixed and embedded in paraffin. The sections were obtained from 40 cases of OLP that were identified by histological examination, as well as 40 cases of OLR. Twenty buccal mucosa samples were obtained from individuals who showed no mouth lesions and did not participate in any oral practices. The study samples were subjected to haematoxylin and eosin stain, as well as a specialized toluidine blue stain. Results: In oral lichen planus, the mast cell counts were 15.25 ± 2.58, which was substantially greater than in OLR (8.63 ± 1.74) and normal oral mucosal tissues (1.99 ± 0.58). The Kruskal-Wallis test was used to compare the average number of mast cells across three groups, and the result was statistically significant ( Conclusion: This experiment's findings point to a greater concentration of mast cells in OLP than in OLR. Because of this, we argue that counting mast cells could be an important histopathological component in pathogenesis of these lichenoid reactions and also help distinguishing OLP from OLR.
