Article in Cancer reports (Hoboken, N.J.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe pathogenesis of diffuse large B-cell lymphoma (DLBCL) remains unclear. Zinc finger protein 382 (ZNF382) expression is significantly downregulated in DLBCL, which is associated with poor prognosis. However, the underlying mechanisms remain unknown.
aimsTo investigate the association between DNA methylation of the promoter region of ZNF382 and ZNF382 expression with the occurrence and progression of DLBCL and to analyze the clinical significance of ZNF382 in DLBCL. METHODS AND
resultsDLBCL cell lines and reactive hyperplastic lymph node tissues were used as the experimental subjects. Methylation-specific polymerase chain reaction and reverse-transcription polymerase chain reaction analyses revealed significantly higher methylation of the promoter region of ZNF382 (p < 0.0001), whereas ZNF382 mRNA expression was significantly lower (p < 0.01) in DLBCL cells compared with those in reactive hyperplastic lymph node tissues. Cells were treated with the demethylating agent decitabine (DAC), and the methylation status of the promoter and expression levels of ZNF382 were determined. ZNF382 promoter methylation was significantly reduced (p < 0.01) in DLBCL cells, whereas ZNF382 mRNA expression was significantly increased (p < 0.01) compared with those in the control cells. Furthermore, compared with that in the blank control group, the apoptosis rate of DLBCL cells was significantly increased following DAC intervention (p < 0.01). A cell model of ZNF382 overexpression was constructed, and its proliferation, migration, and clonogenic capacities were detected using CCK-8, Transwell, and soft agar assays, respectively. Compared with those of the vector control group, the cell proliferation, migration, and clone formation abilities of the ZNF382 overexpression group were significantly inhibited (p < 0.01).
conclusionDNA hypermethylation in the promoter region of ZNF382 and low ZNF382 mRNA expression are closely related to the occurrence and progression of DLBCL. Moreover, ZNF382 overexpression significantly increased apoptosis and inhibited cell proliferation, migration, and clone formation. Therefore, ZNF382 has potential as a therapeutic target in the treatment of DLBCL.
