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

Feed efficiency (Feed conversion ratio, FCR), a critical economic indicator for poultry breeding, is closely associated with the sustainable advancement of the poultry production. However, the molecular mechanisms governing differences in FCR among chickens have not yet been fully elucidated. Transcriptome analysis identified 189 differentially expressed genes, among which NOS2 was identified as a key gene significantly involved in the arginine biosynthesis pathway. Following NOS2 interference for 48 h in primary hepatocytes, CAT, Nrf2, FASN were downregulated, while overexpressed NOS2 showed an opposite tendency. Metabolomics analysis identified 116 and 87 differential metabolites in the liver and cecum contents, respectively. Metagenomics analysis identified s__Methanocorpusculum_vombati as the dominant taxa for LFCR. Integrated analysis revealed that NOS2 expression was positively correlated with 23 liver metabolites. Combined analysis found that genus Oscillibacter as a central hub microbiota, significantly connecting to 2-aminobicyclo[3.1.0]hexane-2,6-dicarboxylic acid in the cecum content. This study elucidates the regulatory role of NOS2 to antioxidant, lipogenesis and inflammatory of chicken hepatocyte, and predicted that NOS2 gene as a central regulator to improve feed efficiency in laying hens.
