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

Mild traumatic brain injury accounts for the majority of head injuries and has been correlated with neurodegeneration and dementia. While repetitive mild traumatic brain injury is highly correlated to neurodegeneration, the correlation of a single mild traumatic brain injury with neurodegeneration is still unclear. Because tau aggregates are the main form of mild traumatic brain injury induced pathology, toxic forms of tau protein most likely play a role in the development of post-mild traumatic brain injury neurodegeneration. Therefore, it becomes crucial to characterize the properties of soluble tau aggregates in single versus repetitive mild traumatic brain injury. Herein, we isolated tau oligomers from wild-type mice exposed to single or repetitive mild traumatic brain injury and characterized the tau aggregates at functional, biochemical and biophysical levels. We demonstrated that single versus repetitive mild traumatic brain injuries frequencies lead to the formation of different tau oligomeric polymorphisms. These polymorphisms express different long-term potentiation impairment potencies, toxicity potentials, morphologies and strain indicating properties. To our knowledge, this is the first evidence that soluble tau oligomers derived from single versus repetitive mild traumatic brain injuries form distinct polymorphisms that possibly correlate with the risk of neurodegeneration after mild traumatic brain injury.
