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
In late-laying hens, the progressive decline in reproductive performance is fundamentally linked to oxidative stress-induced ovarian dysfunction, where conventional dietary selenium (Se) levels often fail to maintain systemic and localized redox homeostasis. The aim of this study was thus to investigate the regulatory effects of supplemental selenium-enriched Lactobacillus plantarum (Se-LP) on production performance, egg quality, Se deposition, and ovarian antioxidant function. A total of 720 hens (63 weeks of age) were randomly assigned to five treatments (8 replicates/group, 18 hens/replicate) and fed either a basal diet (0.275 mg/kg Se) or the basal diet supplemented with 0.1, 0.2, 0.3, or 0.4 mg/kg Se from Se-LP for 8 weeks. Results indicated that dietary supplementation of Se-LP linearly improved the qualified egg rate, egg shape index, eggshell thickness, and Se deposition in eggs (linear, P < 0.05). Se-LP significantly enhanced total antioxidant capacity (T-AOC) and the activities of glutathione peroxidase (GSH-Px) and total superoxide dismutase (T-SOD) in both serum and ovaries (linear, P < 0.05). Se-LP significantly upregulated the mRNA expressions of GPx4, TXNRD1, and TXNRD2, while increasing the transcriptional levels of the key transcription factor Nrf2 in the ovaries (linear, P < 0.05). In summary, dietary supplementation of Se-LP (0.3-0.4 mg/kg) offers a potent nutritional strategy to delay reproductive senescence by reinforcing the Nrf2-mediated antioxidant shield. This not only optimizes eggshell quality and Se-enrichment in commercial production but also extends the functional lifespan of aging laying hens.
