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 investigated the effects of tea polyphenols and compound probiotics on laying performance, egg quality, antioxidant capacity, and intestinal barrier function in Lohmann laying hens. A total of 720 healthy 240-day-old hens (1.78 ± 0.12 kg) were randomly assigned into two dietary groups (six replicates per group, 60 hens per replicate). The control group received a basal diet, while the experimental group was supplemented with 300 mg/kg tea polyphenols and 300 mg/kg compound probiotics for 42 days. Compared to the control group, the experimental group showed a significantly higher laying rate, average egg weight, albumen height, Haugh unit, and eggshell thickness (P < 0.05). Serum catalase activity, total antioxidant capacity, and immunoglobulin A levels increased (P < 0.05), while malondialdehyde levels decreased (P < 0.0001). The experimental group exhibited a significant increase in duodenal villus height and crypt depth, jejunal villus height-to-crypt depth ratio, and ileal crypt depth (P < 0.05). Furthermore, the experimental group exhibited significantly higher threonine, serine, and proline levels in the yolk (P < 0.05). Additionally, nonessential amino acid and total amino acid contents ignificantly increased (P < 0.05), while other amino acids showed an upward trend. Furthermore, cecal microbiota diversity improved, accompanied by an enrichment of beneficial bacterial genera. Functional analysis revealed significant enrichment in key metabolic pathways (P < 0.05). In conclusion, dietary supplementation with tea polyphenols and compound probiotics significantly improved laying performance, egg quality, antioxidant capacity, and intestinal health in Lohmann laying hens.
