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
Background: Methods: Goats were intravenously infected with LM to establish an intracranial infection model. Bacterial loads in brain tissues were quantified, and multiple techniques (immunofluorescence, TUNEL, immunohistochemistry, Western blot, qRT-PCR) were used to detect BBB integrity, apoptotic/autophagic markers, and related pathway proteins (E-cadherin/c-Met, Bcl-2/Bax, LC3B, Pink1/Parkin). Results: LM showed tropism for brainstem regions (midbrain, pons, medulla oblongata) with focal colonization in neurons and glial cells. BBB tight junction proteins (ZO-1, Claudin-1, Occludin) exhibited region-specific dysregulation; notably, an upregulation of Claudin-1 and Occludin was observed in the medulla, suggesting a localized compensatory response. LM infection was associated with the activation of the E-cadherin/c-Met pathway, potentially facilitating transendothelial and neuronal invasion. Apoptosis (Bcl-2/Bax imbalance) and autophagy (LC3B, Pink1/Parkin) were heterogeneously regulated across brain regions, with significant quantitative changes observed in the cerebrum, cerebellum, midbrain, and medulla. Conclusion: LM invades goat brain tissues coinciding with BBB disruption, exhibits brainstem tropism, and modulates apoptosis and autophagy through region-specific pathways, providing novel insights into LM-induced neurological pathogenesis in ruminants.
