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

introductionTibetan sheep, a critical economic livestock species on the Qinghai-Tibet Plateau, are primarily classified into three types: Plateau Tibetan sheep (PT), Valley Tibetan sheep (VT), and Euler Tibetan sheep (EL). This study was the first to compare the growth performance, meat quality, nutritional composition, transcriptome, and flavor metabolome among these three types of Tibetan sheep.

resultsEL exhibited superior growth performance and a higher content of unsaturated fatty acids (UFAs). PT demonstrated advantages in meat quality and flavor characteristics, while VT was distinguished by its unique meat color, specialized amino acid and fatty acid profiles. Transcriptomic analysis revealed breed-specific variations in pathways related to energy utilization, metabolism, and immune function in muscle tissues. Weighted gene co-expression network Analysis (WGCNA) identified key genes (BECN1, CRNKL1, PAB5A, and EIF3A) significantly associated with growth and meat quality traits. Flavor metabolomics showed that VT mutton contained the richest profile of flavor compounds, predominantly contributing to nutty aromas. PT and EL were characterized by higher levels of esters and aldehydes, imparting stronger fruity and floral notes. Integration analysis of differentially expressed genes (DEGs) and metabolites identified COLEC10, MYC, BDNF, and GCGR as potential candidate genes influencing flavor through regulation of lipid and amino acid metabolism.

conclusionThis study systematically characterized the growth performance, meat quality, nutritional composition, and flavor profiles of three Tibetan sheep types. Through multi-omics analysis (transcriptome and metabolome), it uncovered the regulatory mechanisms linking gene expression to meat quality and flavor-related organic compounds. Additionally, potential candidate genes that may improve meat quality and flavor were identified.
