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

The colonic epithelium renews rapidly and must balance proliferation with apoptosis to preserve barrier integrity. We investigated whether grape antioxidant dietary fiber (GADF), a grape pomace-derived dietary fiber matrix naturally rich in high molecular weight non-extractable polyphenols, modulates barrier integrity, through proliferation/cell cycle and apoptosis. To gain mechanistic insight, we examined the role of heat-shock proteins (Hsps), and AMP-activated protein kinase (AMPK)-mTOR-lipid-metabolism signaling in healthy proximal colon. Male Wistar rats received either a cellulose-based control diet or an isoenergetic diet where cellulose was replaced with 5% GADF for four weeks. Morphometric analysis, immunohistochemistry, Western blotting, TUNEL, and caspase activity assays quantified cell cycle, apoptotic, Hsps, and metabolic pathways. GADF strengthened the epithelial barrier, increasing goblet cells, occludin, and ZO-1, while reducing crypt depth. Proliferation was suppressed, as indicated by reduced PCNA, cyclins E and D1, and higher p-p53
