Article in Frontiers in microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Postbiotics are potential functional feed additives, but their effects on multiple health parameters in dogs remain largely unexplored. Methods: This study evaluated postbiotics from Results: No differences were observed in growth performance or routine blood parameters. However, postbiotic supplementation significantly increased serum IgA (LDP and HDP), IgM and IgG (HDP only), and reduced pro-inflammatory cytokines TNF-α and IL-6 (both groups), IL-1β (HDP only), while IL-10 was increased only in LDP. The HDP group showed lower malondialdehyde (MDA); SOD increased in both groups, while GSH-Px and CAT increased significantly only in HDP. Bone formation markers (PINP, OC) increased in HDP. Hair quality improved (smoother cuticle, higher glutamic acid, cysteine, proline) in both groups. Fecal acetic, propionic, and isovaleric acids increased in both groups; valeric acid increased only in HDP. Gut microbiota analysis revealed increased beneficial bacteria (such as Discussion: Bifidobacterium animalis derived postbiotics safely enhance immune function, antioxidant status, bone metabolism, and hair quality in adult dogs, likely via gut microbiota modulation.
