Comparative analysis of intestinal and reproductive function in older laying hens with three egg laying levels.
Article in Frontiers in microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Introduction: In production, older laying hens exhibit different levels of egg production, though these hens with the same genetic background, age, and feeding conditions. It is speculated that this may be due to varying intestinal function in laying hens with different egg production levels. To verify this speculation, this experiment aims to compare the intestinal function in laying hens with different egg production levels. Methods: After a 6-week pre-feeding with 1,000 hens, aged 60 weeks, we observed that the overall egg-laying rate for the flock was roughly 85%. Based on the data, a total of 120 healthy Lohmann Pink laying hens, aged 66 weeks, were selected for the experiment, which established three treatment groups, low egg-laying rate (LR, 76.89% ± 1.65%), medium egg-laying rate (MR, 84.96% ± 1.01%), and high egg-laying rate (HR, 93.12% ± 1.73%). Results: The results indicated that the HR group exhibited significantly enhanced egg production, egg mass, feed efficiency, and qualified egg rate over the 12-week period ( Discussion: These results suggest that hens with higher egg-laying rates demonstrated enhanced production performance and egg quality, which may be attributed to better intestine health (better barrier function, higher enrichment of
