Acute manganese exposure impairs glutamatergic function in a young mouse model of Alzheimer's disease.
Article in Neurotoxicology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Manganese (Mn) is an essential metal that serves as a cofactor for metalloenzymes important in moderating oxidative stress and the glutamate/glutamine cycle. Mn is typically obtained through the diet, but toxic overexposure can occur through other environmental or occupational exposure routes such as inhalation. Mn is known to accumulate in the brain following exposure and may contribute to the etiology of neurodegenerative disorders such as Alzheimer's disease (AD) even in the absence of acute neurotoxicity. In the present study, we used in vitro primary cell culture, ex vivo slice electrophysiology and in vivo behavioral approaches to determine if Mn-induced changes in glutamatergic signaling may be altered by genetic risk factors for AD neuropathology. Primary cortical astrocytes incubated with Mn exhibited early rapid clearance of glutamate compared to saline treated astrocytes but decreased clearance over longer time periods, with no effect of the AD genotype. Further, we found that in vivo exposure to a subcutaneous subacute, high dose of Mn as manganese chloride tetrahydrate (3 ×50 mg/kg MnCl
