1 · What the graph read from it

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.

2 · The registry

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

Neurogranin (Ng), a brain-specific calmodulin-binding protein, is expressed highly in hippocampus, and is important for cognitive function. Deletion of the Ng gene from mice caused attenuation of signal reaction cascade in hippocampus, impairments in learning and memory and high frequency stimulation-induced long-term potentiation (LTP). Environmental enrichment alone failed to improve cognitive function. In this study, behavioral testing revealed that Ng knockout (NgKO) mice were both hyperactive and socially withdrawn. Methylphenidate (MPH) was given to mice while they were also kept under an enrichment condition. MPH treatment reduced the hyperactivity of NgKO mice tested in both the open field and forced swim chamber. MPH improved their social abilities such that mice recognized and interacted better with novel subjects. The cognitive memories of MPH-treated mutants were improved in both water maze and contextual fear conditioning tests. High frequency stimulation-induced LTP of NgKO mice was also improved by MPH. The present treatment regimen, however, did not fully reverse the deficits of the mutant mice. In contrast, MPH exerted only a minimal effect on the wild type mice. At the cellular level, MPH increased the number of glial fibrillary acidic protein-positive cells in hippocampus, particularly within the dentate gyrus of NgKO mice. Therefore it will be of interest to determine the nature of MPH-mediated astrocyte activation and how it may modulate behavior in future studies. Taken together these NgKO mice may be useful for the development of better drug treatment to improve cognitive and behavioral impairments.
