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
Objectives: The aim of this study is to investigate the role of epithelial cell transforming sequence 2 (ECT2) as a pan-cancer biomarker and to assess its potential as an immune-related target for cancer immunotherapy. Methods: We conducted a comprehensive analysis of ECT2 expression across 44 tumor types using large-scale transcriptomic datasets from The Cancer Genome Atlas (TCGA) and the Genotype-Tissue Expression (GTEx) project. Pan-cancer Cox regression analyses were performed to evaluate the correlation between ECT2 expression and patient survival outcomes. Functional assays, including ECT2 knockdown via shRNA in the HepG2 hepatocellular carcinoma (HCC) cell line, were employed to investigate its mechanistic role. Transcriptomic profiling and pathway analyses were also conducted to explore the impact of ECT2 on cell proliferation and the tumor immune microenvironment. Results: ECT2 was found to be significantly upregulated in 31 tumor types. Elevated ECT2 expression was consistently associated with worse overall survival (OS), disease-specific survival (DSS), disease-free interval (DFI), and progression-free interval (PFI) across multiple cancer subtypes. Functional assays revealed that ECT2 knockdown significantly reduced HepG2 cell viability and impaired cell cycle progression, with downregulation of Cyclin D1. Transcriptomic analysis of ECT2-depleted cells indicated enriched gene sets related to cell proliferation and mitotic regulation. Additionally, ECT2 expression was significantly correlated with immune features, including immune cell infiltration, immune checkpoint gene expression, tumor mutational burden (TMB), and microsatellite instability (MSI). Conclusion: ECT2 is identified as a potential pan-cancer prognostic biomarker with dual roles in tumor initiation and progression, as well as in modulating the tumor immune microenvironment. Our findings suggest that ECT2 may serve as a promising therapeutic target in cancer immunotherapy, warranting further investigation into its immune-regulatory and oncogenic functions.
