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
Psoriasis is a chronic immune-mediated disease characterized by an interplay between the immune cells and keratinocytes. Currently, plant extracts have attracted more attention due to their potential value in medicine. Anagyris foetida L. is a flowering plant of the Fabaceae family that grows in the Mediterranean region. Traditionally, it has been used to treat eczema. Their leaves are rich in bioactive compounds that may contribute to psoriasis treatment. The present study evaluates the therapeutic efficacy of A. foetida leaf extracts compared to clobetasol in an imiquimod-induced psoriasis mouse model. Sequential extraction of A. foetida leaves using solvents of increasing polarity. Ointments prepared from each extract were tested in a psoriasis-induced model. Seventy male mice were randomly divided into seven groups of ten mice each. The current study investigated clinical observations, PASI and Baker’s scores, histopathological assessments, and inflammatory biomarkers. Subsequently, the most efficient extract was analyzed by High-Performance Liquid Chromatography (HPLC). Among the tested extracts, the ethanol extract demonstrated the strongest anti-psoriatic activity, as evidenced by a significant reduction in PASI scores, improvements in epidermal hyperplasia and inflammatory infiltration on histopathological examination, and a significant reduction of psoriasis-related inflammatory cytokines. HPLC analysis identified N-methylcytisine and isorhamnetin, which may contribute to the observed pharmacological activity. The ethanol extract of A. foetida leaves significantly alleviated psoriasis-like inflammation in the imiquimod-induced mouse model, supporting its potential as a natural anti-psoriatic therapeutic candidate.
