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

Conventional poultry breeding primarily targets host growth traits, yet breeding may also reshape the gut microbiota through host-microbe interactions. Given the spatial heterogeneity of the chicken gastrointestinal tract, whether divergent selection for body weight is associated with compartment-specific microbial assembly and differences in the digestive ecosystem remains unclear. Here, using female primitive line and a high body weight (HBW) selected line, we systematically characterized differences in host gastrointestinal traits and gut microbial ecology associated with divergent selection history. Significant differences in gut morphology and local environmental conditions were observed between the two lines, together with region-specific shifts in microbial community assembly. Specifically, crop weight was greater and microbial assembly exhibited greater stochasticity in the HBW line, potentially reflecting differences in feeding-related gastrointestinal dynamics. In contrast, the small intestine displayed improved villus morphology and altered microbial assembly patterns, accompanied by enrichment of potentially beneficial taxa associated with nutrient utilization, including Monoglobus in the duodenum and Blautia in the ileum, indicating coordinated changes in host intestinal development and microbial ecological adaptation. The cecal community showed relatively stable assembly patterns but was enriched in metabolically relevant taxa such as Lachnospiraceae and Faecalibacterium, together with differences in predicted functional potential related to nutrient metabolism. Overall, this study shows that the HBW line is associated with distinct, compartment-specific patterns of gut microbial assembly, providing a conceptual framework for considering the gut microbiota in poultry breeding strategies.
