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
introductionHeart failure (HF) is a progressive condition with complex molecular mechanisms. This study aims to identify potential biomarkers and therapeutic targets by analyzing differentially expressed genes (DEGs) in HF patients, exploring the roles of hub genes, and developing a risk model for predicting disease progression. METHODOLOGY: We cultured five human HF cell lines and five normal coronary cardiomyocyte cell lines. Gene expression datasets were retrieved from the Gene Expression Omnibus (GEO) database and analyzed using limma. Protein-Protein Interaction (PPI) networks were constructed with STRING, and immune cell infiltration was analyzed using CIBERSORT. A risk model was built using LASSO regression. Drug screening was performed via CMap, and overexpression studies of CCND1 and HIF1A were conducted in AC16 and SEKHEP1 cells via cell proliferation, colony formation, and wound healing assays.
resultsWe identified 182 common DEGs associated with HF. Hub genes CCND1, GABPA, HIF1A, and SOX6 were central in the PPI network. LASSO regression established a risk model linked to disease progression. Immune infiltration analysis revealed altered immune cell profiles in HF. The miRNA-mRNA network showed interactions of hsa-miR-93-5p, hsa-miR-802, hsa-miR-199a-5p, and hsa-miR-203a-3p with hub genes. Overexpression of CCND1 and HIF1A in cell lines impaired proliferation, colony formation, and migration, implicating their role in HF pathophysiology.
conclusionCCND1, GABPA, HIF1A, and SOX6 may serve as biomarkers for HF. Our findings provide valuable insights into immune infiltration, miRNA regulation, and the identification of therapeutic targets for HF management. These results highlight the role of gene regulation in HF progression and may guide future therapeutic interventions.
