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

backgroundEpstein-Barr virus-associated gastric cancer (EBVaGC) accounts for ~ 10% of gastric cancers (GC). Programmed death-ligand 1 (PD-L1) expression plays a key role in immune evasion and response to immunotherapy, but its correlation with EBVaGC remains unclear.

methodsWe searched PubMed, Embase, and Cochrane databases for studies evaluating PD-L1 expression in EBVaGC. The primary outcome was the association between EBV and PD-L1 expression. Statistical analyses were performed using RStudio.

resultsA total of 53 studies with 17,806 patients were included. PD-L1 expression in EBVaGC was 10.34% (95% CI: 6.30-14.38; I

conclusionOur findings reinforce the relevance of molecular classification, particularly the assessment of Epstein-Barr virus status, as a promising tool for improving patient stratification and guiding therapeutic decisions in gastric cancer. These results may contribute to advancing future research aimed at validating and expanding the use of these biomarkers globally.
