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
Objectives: Oral lichen planus (OLP) is a chronic inflammatory mucosal disease with an incompletely understood pathogenesis. This study aimed to investigate the role of disease-specific fibroblasts in OLP. Methods: We performed single-cell RNA sequencing on buccal mucosa of 4 OLP patients and one healthy control. Additionally, mRNA expression and immunofluorescence staining were analyzed in primary fibroblasts from 51 OLP patients and 24 healthy individuals. The spatial cellular interactions were assessed using multiplex immunofluorescences in OLP tissues. Results: Using single-cell RNA sequencing, we identified SFRP2+ fibroblasts as the origin of inflammatory fibroblasts in OLP. A subset of SFRP2+ fibroblasts specifically expressed Wnt5a and was implicated in antigen processing and presentation pathway in OLP. Furthermore, SFRP2+Wnt5a+ fibroblasts amplified and maintained the local immune inflammation by interacting with CD8+ T cells and epithelial cells. Compared to the healthy control group, upregulated expressions of pro-inflammatory molecules (CXCL12, CXCL14) and antigen presenting associated molecules (HLA-A, HLA-B, HLA-C and ERAP2) were displayed in OLP group at mRNA level. Colocalization of SFRP2 and Wnt5a was displayed in the primary cultured fibroblasts of OLP Conclusions: Our findings reveal the heterogeneity and pathogenic mechanisms of fibroblasts in OLP, providing new insights into the cellular drivers of chronic inflammation in OLP.
