A Comparative Study of Genital Lichen Sclerosus Transcriptomes.
Article in Acta naturae. 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
Genital lichen sclerosus (GLS) is a chronic inflammatory dermatosis that affects the genital skin. Despite different clinical manifestations, the pathogenesis of GLS in men and women is believed to be common and is attributed to a combination of autoimmune and genetic factors. In this study, we compared the transcriptomic profiles of penile (mGLS) and vulvar lichen sclerosus (VLS), aiming to identify commonly deregulated genes. We observed a substantial heterogeneity in the transcriptomic signatures in mGLS samples, which is driven by different compositions of immune infiltrates. In mGLS, gene expression signatures strongly indicate epidermis dysfunction and overexpression of the epithelial inflammation marker Keratin 6 (KRT6) and chitinase CHIT1. No significant changes in the expression levels of known GLS markers, such as VIM, CTNNB1, LGALS7 and ECM1, were detected. However, significant changes in the expression levels of the genes associated with autoimmune diseases and the genes upregulated in squamous cell carcinoma, including TNF, CCNB1 and RUNX3, were observed. There was no enrichment in the polyU/UC insertions that were reported previously. Instead, we have identified a long non-coding RNA DRAIC with a high coding potential that is commonly upregulated in mGLS and VLS. Taken together, our results provide a comprehensive picture of the shared transcriptomic signatures, including novel biomarkers and potential therapeutic targets.
