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
Purpose: Psoriasis is an immune-related disorder characterized by silver scales, epidermis thickness, and itching. She-Chuang-Si-Wu-Tang (SSWT), a traditional Chinese medicine decoction, has been used clinically for 400 years. Although it benefits psoriasis treatment, the mechanism of action is still unclear. This study explores SSWT's molecular mechanism in treating psoriasis through network pharmacology analysis and experiments. Methods: We identified relevant SSWT and psoriasis targets using network pharmacology and conducted SSWT quality control with high-performance liquid chromatography (HPLC). A mouse model of psoriasis was established using imiquimod (IMQ), with the drug administered continuously for seven days, spanning an eight-day period. During the experiment, we observed spontaneous scratching behaviors and assessed the Psoriasis Area and Severity Index (PASI) scores. At the conclusion of the experiment, we examined skin tissue pathology under an optical microscope and measured epidermal thickness. Additionally, we used enzyme-linked immunosorbent assay (ELISA) and quantitative reverse transcription polymerase chain reaction (qRT-PCR) to measure interleukin (IL)-23, IL-17A, IL-17F, and interferon (IFN)-γ levels in the mice's serum and their mRNA expression in the skin. Western blot analysis was conducted to assess protein levels related to signaling pathways. Results: Results indicate that SSWT may target IL-17 signaling pathways and T helper (Th) 17 cell differentiation, as predicted by network pharmacology. SSWT significantly improved the PASI and Baker scores, reduced epidermal thickness, and decreased spontaneous scratching in IMQ-induced mice. Additionally, SSWT treatment significantly lowered the concentrations of inflammatory factors in the serum and skin lesions, as well as mRNA expression levels, compared to the IMQ group. Furthermore, SSWT significantly inhibited the phosphorylation of both the signal transducer and activator of transcription 3 (STAT3) and mitogen-activated protein kinase (MAPK) pathways. Conclusion: In summary, this study unveiled the potential anti-psoriatic mechanism of SSWT, offering new evidence for its clinical application.
