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

This study aimed to elucidate the molecular mechanism of cecal microbiota regulating muscle flavor in Yanshan red jade broilers with natural body weight variation. Eighteen-week-old hens were selected for this study. Targeted metabolomics was applied to determine the fatty acid and amino acid composition of muscle. Metagenomic sequencing was used to analyze the structure and function of cecal microbial communities. A regulatory network between gut microbiota and meat flavor was constructed via correlation analysis. The results showed that the high-weight female (HF) group had significantly better slaughter performance and leg muscle intramuscular fat (IMF) than the low-weight female (LF) group. Metabolomic analysis identified a total of 38 fatty acids and 25 amino acids. The HF group was enriched in umami amino acids such as arginine and serine, while the LF group had higher content of long-chain polyunsaturated fatty acids (PUFAs) and 1-methyl-l-histidine. Metagenomic analysis showed that Eubacterium and Anaerostipes were the characteristic bacteria in the HF group, while Odoribacter was dominant in the LF group. Functional annotation identified a total of 12 differential metabolic pathways, including core pathways such as lipid metabolism and amino acid synthesis. The association network showed that Eubacterium sp. An11 enhanced growth performance and umami quality by promoting muscle protein deposition, Odoribacter_splanchnicus affected muscle nutritional characteristics by regulating fatty acid metabolism, and Pseudoflavonifractor_capillosus was involved in both growth and flavor regulation. This study provides theoretical support and functional strain targets for flavor improvement of high-quality broilers and precise nutritional regulation of gut microbiota.
