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
Background and Aim: Seaweeds, particularly brown seaweed (BS) and green seaweed (GS), are rich in bioactive compounds that may enhance poultry health and productivity. This study evaluates the effects of dietary BS and GS on blood plasma immunoglobulin concentrations, mucosal immunity, small intestine histomorphology, cecal microbial populations, and volatile fatty acid (VFA) profiles in broiler chickens. Materials and Methods: A total of 504 one-day-old male broilers were randomly assigned to 12 dietary treatments: A negative control (basal diet), a positive control (basal diet + 100 mg/kg Vitamin E), and diets supplemented with BS and GS at 0.25%, 0.50%, 0.75%, 1.00%, and 1.25%. The study followed a completely randomized design, with data analyzed using a one-way analysis of variance and Duncan's multiple range test (p < 0.05). Results: Broilers fed 0.75%, 1.00%, and 1.25% GS exhibited significantly higher (p < 0.05) blood plasma immunoglobulin A (IgA) and immunoglobulin G (IgG) concentrations. Dietary BS and GS inclusion upregulated messenger RNA expression of interleukin-6, interleukin-10, and interferon-gamma, indicating immunomodulatory effects. Jejunal villus height was significantly increased in birds fed 0.50%, 0.75%, and 1.25% BS during the starter period. Birds receiving 0.50% BS, 0.25% GS, and 0.50% GS exhibited higher cecal Conclusion: The inclusion of GS (0.75%, 1.00%, and 1.25%) in broiler diets enhances immune response by increasing IgA and IgG levels. Both BS and GS positively modulate cytokine expression, intestinal morphology, and microbial balance, leading to improved gut health. The results suggest that BS and GS supplementation may serve as sustainable feed additives to enhance broiler performance while reducing reliance on synthetic supplements. Future studies should focus on identifying the bioactive compounds responsible for these effects and their broader implications for poultry production.
