1 · What the graph read from it

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.

2 · The registry

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

backgroundA substantial portion of gastric cancer (GC) is linked to Epstein-Barr virus (EBV) infection. The characteristics of this viral genome, such as specific viral strains and large structural variations, influence the progression of diseases like nasopharyngeal carcinoma and hematological malignancy. However, the EBV genomes from GC have not been thoroughly characterized.

methodsOur study involved 849 consecutive GC patients diagnosed at Nagoya City University Hospital, Japan (NCU cohort). We detected EBV from formalin-fixed, paraffin-embedded sections using a novel direct PCR-based rapid detection method. Additionally, we analyzed 142 EBV whole genomes (125 newly sequenced) from GC, comparing them with 205 genomes from other EBV-associated diseases.

resultsWe identified 32 (3.8%) patients associated with EBVaGC in the NCU cohort. Moreover, the direct PCR identified several GC specimens containing EBV-infected lymphocytes or their follicles. The dominant viral strain in GC was type 1 EBV, prevalent in most parts of the world, and no GC-specific strain was identified. We found no significant associations between single-nucleotide variants in the viral genome and GC. Structural variations of the EBV genome were infrequent in GC (4 cases, 2.1%), contrasting with EBV-associated hematological malignancy, which frequently carries large deletions.

conclusionsThis study is the first to uncover the genomic variations of EBV in GC. While EBV is definitively linked to GC, the characteristics of its genomes do not strongly correlate with disease development or progression. Our findings on viral genomes supplement the current understanding of human genomes in EBVaGC.
