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
INTRODUCTION AND
aimsOral squamous cell carcinoma (OSCC) is a common malignant tumour of the head and neck region. In recent years, the relationship between pyroptosis and tumours has received increasing attention. However, its regulatory mechanism and effects on tumour behaviour remain unclear. The purpose of this study was to explore the effect of chemerin expression on pyroptosis of OSCC tumour cells and its underlying molecular mechanism.
methodsIn this study, chemerin expression and pyroptosis-related proteins in 145 OSCC tissues were detected using immunohistochemical methods. The effect of chemerin expression on the expression of pyroptosis related proteins (GSDMD,GSDMD-N and IL-1β) in OSCC cells was explored by Western blot analysis. The influence of chemerin-induced pyroptosis on the proliferation, migration, invasion, epithelial-mesenchymal transition (EMT) and lipid metabolism of OSCC cells was investigated through scratch test, transwell, flow cytometry experiments and CCK-8 assays. Nude mice experiments were also done to explore the effects of chemerin expression on tumour cell pyroptosis and tumour growth.
resultsOur findings suggested that elevated expression of chemerin enhances pyroptosis in OSCC cells both in vivo and in vitro. Pyoptosis-related proteins were highly expressed in OSCC, and Gasdermin D (GSDMD) expression was associated with poor clinical prognosis and short survival time in OSCC patients. The combination of chemerin and GSDMD expression was correlated with a poorer clinical prognosis. In vitro experimental results showed that pyroptosis of OSCC cells promoted cell proliferation by regulating cell cycles via increasing the number of cells entering the S phase, as well as cell invasion and migration through EMT. The pyroptosis of OSCC cells also affected lipid metabolism, promoting tumour progression.
conclusionOur findings indicate that chemerin mostly facilitated pyroptosis of OSCC cells via the NLRP3/GSDMD-N pathway, and pyroptosis promoted tumor progression through different pathways. Both overexpression of chemerin and elevated pyroptosis in OSCC cells appear to be poor prognostic jndicators in OSCC.
