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
backgroundThe improvement of meat quality by selenium (Se) supplementation has been well documented; however, the effects and underlying mechanisms by which Se-enriched yeast modulates meat quality remain unclear. This study aimed to investigate the effects of Se-enriched yeast on meat quality and its molecular characteristics in finishing pigs. All pigs were fed a Se-deficient diet (SeD) or the same diet supplemented with 0.3, 1, 3, or 5 mg Se/kg (CT, SY1, SY3, and SY5).
resultsCompared with SeD, Se-enriched yeast supplementation, especially SY3, improved marbling score, intramuscular fat content, antioxidant capacity, and fatty acid composition in the LD muscle (P < 0.05). Lipidomic analysis revealed that Se-enriched yeast supplementation altered the abundances of multiple lipid species, while transcriptomic analysis showed significant enrichment of pathways related to unsaturated fatty acid and glycerophospholipid metabolism (P < 0.05). Integrated analyses further identified glycerophospholipid metabolism as a key pathway associated with major lipids, including phosphatidylcholine (PC) and phosphatidylethanolamine (PE), along with regulatory genes glycerol-3-phosphate acyltransferase 3 (GPAT3) and phosphatidylserine decarboxylase (PISD). Correlation analysis indicated that stearoyl-CoA desaturase (SCD), elongation of very long chain fatty acids protein 4 (ELOVL4), and GPAT3 play crucial roles in lipid synthesis.
conclusionSe-enriched yeast supplementation at 3 mg/kg improved meat quality, primarily through the regulation of glycerophospholipid metabolism, enhancement of membrane stability, and lipid homeostasis. These findings offer mechanistic insights into the role of Se-enriched yeast and highlight its potential as an effective feed additive for improving meat quality in finishing pigs.
