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
backgroundThis study examines the roles of Cyclin B1 (CCNB1), Polo-Like Kinase 1 (PLK1), and Heparanase (HPSE) in breast cancer progression using a multi-omics approach. These genes are known for their involvement in various cancer-related processes, but their precise contributions to breast cancer remain unclear.
methodsWe employed an integrative analysis combining transcriptomics, proteomics, DNA methylation profiling, immune infiltration analysis, and single-cell RNA sequencing to investigate the expression patterns, regulatory mechanisms, and functional impacts of CCNB1, PLK1, and HPSE in breast cancer. Functional assays using si-RNA knockdown of CCNB1 and PLK1 were performed to assess their roles in cell proliferation.
resultsCCNB1, PLK1, and HPSE are upregulated in breast tumors at the mRNA and protein levels. CCNB1 and PLK1 promote tumor growth and metastasis, while HPSE is linked to immune pathways. DNA methylation in BRCA correlates with prognosis, with PLK1 alterations protective for recurrence-free survival. High expression of these genes worsens prognosis, with CCNB1 as a risk factor for overall survival. Immune infiltration analysis associates these genes with tumor-infiltrating immune cells, highlighting HPSE's immunotherapeutic potential. Single-cell RNA sequencing confirms CCNB1 and PLK1 drive malignant proliferation and an immunosuppressive environment. Functional assays demonstrated that silencing CCNB1 and PLK1 significantly reduced breast cancer cell proliferation, indicating regulatory interactions among PLK1, CCNB1, and MKI67.
conclusionsThis study provides evidence that CCNB1, PLK1, and HPSE are key players in breast cancer progression and potential biomarkers for prognosis. Furthermore, their roles in immune regulation suggest they could be promising targets for immunotherapy.
