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

Almond-derived peptide fractions (APs) represent a promising yet underexplored class of plant-based bioactive compounds for ulcerative colitis (UC) management. This study investigated the protective effects of APs against dextran sulfate sodium (DSS)-induced colitis in male BALB/c mice using integrated 16S rRNA sequencing and transcriptomic analysis. Mice received low-dose (200 mg/kg) or high-dose (400 mg/kg) APs during 7-day DSS administration. Both doses significantly attenuated body weight loss, disease activity index, colon shortening, and histopathological damage. Compared with the DSS group, low-dose and high-dose APs reduced disease activity index by 65.9% and 52.4%, increased colon length by 30.0% and 26.5%, decreased histopathological scores by 39.6% and 55.1%, and lowered colonic myeloperoxidase activity by 13.9% and 34.1%, respectively. APs also modulated inflammatory cytokines, improved mucus-barrier-related indices, and enhanced continuous ZO-1 localization at epithelial junctions. Additionally, 16S rRNA sequencing indicated that AP treatment was associated with altered genus-level microbiota profiles after DSS exposure, including changes in Ligilactobacillus, Escherichia-Shigella, and Parabacteroides-related taxa. Transcriptomic analysis suggested dose-associated response patterns: low-dose APs were associated with broader immune-related transcriptional changes, whereas high-dose APs were more closely associated with extracellular matrix organization, focal adhesion, and genes enriched in the PI3K-Akt signaling pathway. These findings support the protective effects of APs in DSS-induced acute colitis and suggest potential associations among microbiota alterations, host transcriptional responses, and mucosal repair.
