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
Lymphatic metastasis (LM) remains a major contributor to mortality among patients with head and neck squamous cell carcinoma (HNSCC). Understanding the molecular mechanisms underlying LM and identifying novel therapeutic targets are critical priorities. This study investigated ADAM22, a protein implicated in cell adhesion, migration, and differentiation, for its role in HNSCC and its association with LM. Its expression levels were evaluated in HNSCC tissues with and without LM using quantitative real-time PCR (qRT-PCR), western blotting, and immunohistochemistry. The prognostic relevance of ADAM22 was analyzed through Kaplan-Meier survival curves and Cox proportional hazards models. Functional assays, including EdU incorporation, flow cytometry, wound healing, and Transwell migration assays, were performed in FADU and SCC15 cell lines alongside an in vivo footpad xenograft mouse model. ADAM22 was found to be significantly overexpressed in HNSCC cases with LM. In vitro, silencing of ADAM22 suppressed tumor cell proliferation, migration, and invasion and promoted apoptosis. Both in vitro and in vivo experiments demonstrated that ADAM22 enhances tumor growth and lymphatic spread by promoting epithelial-mesenchymal transition (EMT). Further analysis identified integrins as key mediators in ADAM22-driven EMT and metastasis. In summary, these findings indicate that ADAM22 promotes LM in HNSCC by regulating EMT through integrin signaling, highlighting its potential as a therapeutic target and providing new perspectives for diagnosing and treating HNSCC.
