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

American tackle football is associated with high rates of concussion, leading to neurophysiological disturbances and debilitating clinical symptoms, but previous investigations have largely ignored aperiodic neurophysiological activity. In this study, we use pre- and post-season resting-state magnetoencephalography (MEG) to examine whether concussion during a season of football is related to changes in neurophysiology and whether any such changes are associated with clinical outcomes. Concussion was associated with increased aperiodic exponents in superior frontal cortices, indicating a relative reduction in cortical excitability, which accounted for effects on raw delta and gamma power and was associated with worse cognitive concerns across participants. Subtler effects of non-concussive head-impact exposure on neurophysiology were similar to those of concussion. These findings indicate that concussion alters the excitability of the cortex, similar to much more subtle effects of non-concussive exposure.
