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

Residual feed intake (RFI) is a key indicator of feed efficiency in poultry. Although regulatory links such as the hypothalamus-gut and gut-liver axes have been implicated, most studies remain restricted to single axes or fragmented analyses, and systematic multi-organ integration is lacking. Here, we measured feed efficiency in 1,000 Nonghua ducks and selected 12 individuals with divergent RFI for transcriptomic profiling of the hypothalamus, pituitary, liver, duodenum, jejunum, ileum, and cecum, combined with serum metabolomics. We identified 769 differentially expressed genes (DEGs), with the hypothalamus, liver, and cecum as major contributors, and 28 differential serum metabolites enriched in lipid and amino acid metabolism. Beyond tissue-specific functions, enrichment analysis highlighted several pathways that were repeatedly shared across central and peripheral tissues, including neuroactive ligand-receptor interaction, hormone signaling, steroid hormone biosynthesis, and insulin signaling, suggesting a coordinated regulation of feed efficiency between the brain, gut, and liver. To clarify their relevance, we integrated gene modules with metabolites and identified two candidate cross-organ association frameworks: the MEblack-6-Oxopiperidine-2-carboxylic acid (gut-liver) networks, enriched for liver genes CNTNAP1, SHC3, and RAB36, and cecal genes DCC and CCDC60. The MEblue-LysoPE(18:2(9Z,12Z)/0:0) (gut-brain) networks, enriched for cecal genes FABP6, KCNJ11, and the pituitary gene TRPA1, in which these genes and metabolites may contribute to RFI regulation. Together, these findings provide new insights into cross-organ molecular networks underlying feed efficiency in ducks and establish a valuable resource for future functional studies and breeding strategies.
