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

Digestive system cancers (DSCs) remain among the most prevalent and lethal malignancies worldwide, accounting for more than a quarter of cancer diagnoses and a third of cancer deaths. Advances in next-generation sequencing (NGS) have accelerated discovery of genetic, epigenetic, and transcriptomic alterations, yet an integrated overview across DSCs is lacking. This scoping review synthesized 57 studies published between 2013 and 2025 from PubMed, Scopus, and Web of Science. Colorectal and gastric cancers were most frequently represented, while oesophageal, pancreatic, and rare subtypes such as gallbladder and ampullary cancers were under-studied. Recurrent alterations in TP53, KRAS, PIK3CA, and CDKN2A were identified, alongside mismatch repair deficiency and microsatellite instability in colorectal and gastric cancers. Emerging evidence from recently published studies further highlights the contribution of germline alterations and increased molecular heterogeneity in selected DSC subtypes. Epigenetic dysregulation and recent applications of single-cell and spatial transcriptomics highlighted tumour heterogeneity. Despite progress, evidence remains uneven across cancer types, with limited exploration of germline variants beyond colorectal, pancreatic, and select liver cancers.
