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
Saccharomyces cerevisiae fermentation product (SCFP), a postbiotic feed additive, has potential to improve animal growth and productivity. However, its effects on post-peak laying hens have not been thoroughly investigated. Therefore, this study aimed to explore the effects of SCFP on production, egg quality, intestinal health, ovarian function, and cecal microbiota in post-peak laying hens. A total of 600 45-week-old Lohmann pink laying hens were randomly assigned into three treatments, with ten replicates and twenty hens per replicate. The hens were fed either a basal diet (CON) or basal diet supplemented with SCFP at 750 mg/kg (SCFP1) and 1250 mg/kg (SCFP2) for 16 weeks. The results showed no significant effects on the laying performance (P > 0.05). SCFP supplementation increased Haugh unit, yolk color, albumen height, and eggshell ratio compared to the CON diet(P < 0.05). Hens received SCFP diets exhibited a higher intestinal villus height-to-crypt depth ratio (P < 0.05) and up-regulated the expression of jejunal occludin, zonula occluden-1 (ZO-1), and mucin 2 (MUC-2) (P < 0.05). Additionally, SCFP supplementation increased the concentration of jejunal secretory immunoglobulin A (SIgA) (P < 0.05), elevated serum levels of immunoglobulin A (IgA), IgG, interleukin-10 (IL-10), and interferon-γ (IFN-γ) (P < 0.05). Furthermore, dietary SCFP tended to decrease ovarian cell apoptosis and enhanced antioxidant capacity in laying hens (P < 0.05). Compared to CON group, the SCFP1 and SCFP2 groups had lower total bacteria and Escherichia coli, higher Lactobacillus (P < 0.05), and a greater abundance of Streptococcus, Pedosphaerales, Christensenellales, and Prevotellaceae in cecum. Significant correlations were observed between egg quality, intestinal health, ovarian function, and cecal microbiota. In addition, cecal microbial functional prediction indicated that SCFP altered various nutritional metabolism pathways. Dietary SCFP supplementation effectively improved egg quality in post-peak laying hens by modulating intestinal health, ovarian function, and cecal microbiota. Collectively, SCFP could be used as a valuable feed additive for post-peak laying hens, with 1250 mg/kg SCFP showing the better effects.
