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

backgroundObesity is a global health concern linked to metabolic disorders and gut microbiota dysbiosis, particularly under high-fat diet (HFD) conditions. This study explores the role of imidazole propionate (ImP), a histidine-derived microbial metabolite, in regulating lipid metabolism and the development of obesity.

methodsMale C57BL/6 mice were fed either a chow diet or HFD for 15 weeks, followed by plasma metabolomic analysis, which revealed significant downregulation of ImP in obese mice. Functional assays were performed using zebrafish larvae and human adipocytes, with lipid accumulation assessed via Nile Red and Oil Red O staining. Transcriptomic sequencing and KEGG pathway analysis were used to investigate the underlying molecular mechanisms.

resultsImP treatment notably reduced lipid accumulation in both zebrafish larvae and human adipocytes. RNA-seq and protein expression analyses revealed that ImP suppressed peroxisome proliferator-activated receptor (PPAR) pathway key components, such as FABP4, ACSL4, and CEBPα.

conclusionsThese findings demonstrate that ImP attenuates lipid accumulation by inhibiting the PPAR signaling pathway. As a gut microbial metabolite, ImP may offer therapeutic potential in preventing or treating HFD-induced obesity.
