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

backgroundGastric intestinal metaplasia (GIM) is a precancerous lesion closely associated with gastric cancer (GC) risk. A systematic characterization of the molecular profiles across distinct cell types during GIM progression is crucial for devising new intervention strategies and enabling early prevention for GC.

methodsThis study integrates single-cell transcriptomics and proteomics data from gastric tissues of patients with mild chronic non-atrophic gastritis (CNAG) and moderate-to-severe GIM.

resultsWe identified differentially expressed genes (DEGs) and proteins (DEPs) that show consistent changes at both transcriptional and protein levels across epithelial, stromal, and immune cells. Notably, most proteins were downregulated in GIM tissues, potentially linked to reduced expression of RNA splicing-related genes. Epithelial cells in GIM lesions exhibited intestinal-type subpopulations, including goblet and enterocytes, likely originating from gastric isthmus stem cells. Despite overall protein downregulation, the ubiquitin-like protein NEDD8 was markedly upregulated in metaplastic tissues, especially in H. pylori-positive tissues. Pathways involved in cytoskeleton maintenance, extracellular matrix stability, and cell adhesion were downregulated, while several macrophage-expressed DEGs/DEPs (e.g., BST2, CYBB, ITGB2) were elevated.

conclusionsThis work delineates dynamic transcriptional and translational alterations during the progression from mild gastritis to GIM. It implies that chronic inflammatory injury causes suppress protein synthesis, further driving metaplastic transformation early gastric precancerous lesions.
