Emulsifiers in poultry nutrition-molecular mechanism of lipid metabolism and energy utilization: A meta-analysis and KEGG mapping.

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.
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 feed energy derived from fat remains relatively low because young poultry have limited fat digestibility and inefficient lipid metabolism. This study aimed to evaluate the effectiveness of emulsifiers in regulating lipid metabolism and increasing lipase activity in poultry. A quantitative review of 57 studies (2015-2025) revealed that emulsifier supplementation significantly upregulated genes associated with lipogenesis, including diacylglycerol O-acyltransferase 2 (DGAT2), and increased lipolysis through the upregulation of perilipin 1 (PLN1). It also increased the activities of lipoprotein lipase and total lipase. Kyoto Encyclopaedia of Genes and Genomes (KEGG) mapping also suggested that fatty acid biosynthesis (gga00061), β-oxidation (gga00071), the PPAR signalling pathway (gga03320), cholesterol metabolism (hsa04979), and the regulation of lipolysis (gga04923) in adipocyte regulation pathways were synergistically activated. Taken together, these pathways suggest that emulsifiers improve lipid turnover, oxidative metabolism and lipoprotein formation in broiler chickens. In summary, emulsifiers modulate lipid metabolism at the molecular level, which offers mechanistic support for improving energy utilization and may also aid in developing precision nutrition strategies in poultry.
