1 · What the graph read from it

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.

2 · The registry

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

Background: Psoriasis is a chronic inflammatory skin disease involving dysregulated immune responses and complex genetic factors. This study combines single-cell RNA sequencing (scRNA-seq), gene expression profiling, and genetic analysis to explore cellular and molecular contributors to psoriasis. Methods: Single-cell RNA-seq data (n = 3 psoriasis, n = 2 control; GSE228421) were used for cell-type annotation and functional characterization. T cell subsets were analyzed for differentiation trajectories and cell-cell communication. Differentially expressed genes in mucosal-associated invariant T (MAIT) cells were evaluated by enrichment analysis. Candidate gene causality was tested via eQTL-based Mendelian randomization (MR) and supported by bulk RNA-seq validation. Results: MAIT cells were enriched in psoriatic lesions and exhibited strong intercellular interactions. Functional analyses revealed activation of IL6-JAK-STAT3 signaling, TNF-NFκB pathway, and glycolysis in MAIT cells. MR identified RPS20 as a protective factor (OR = 0.5994, p = 0.011) and PFN1 as a potential risk gene (OR = 1.7229, p = 0.037), with PFN1 highly expressed in MAIT cells. Colocalization analysis showed no significant genetic overlap between PFN1 expression and psoriasis risk. Metabolic profiling revealed differential pathway involvement in PFN1+ and PFN1- MAIT cells. Conclusion: Our integrative analysis highlights MAIT cells and PFN1 as likely contributors to psoriasis pathogenesis. These findings offer insights into immune and metabolic alterations, suggesting potential targets for therapeutic intervention.
