Review in Translational stroke research, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.

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

The long-term effects of multiple sport-related concussions are currently at the center of debate in the popular press and scientific community. The question, "How many concussions are too many," is frequently asked in the competitive sport environment by parents, athletes, and coaches. While research suggests that a history of concussion influences the risk and recovery from subsequent concussion, studies investigating the long-term effects of multiple concussions are less conclusive. This paper reviews the literature on multiple concussions and the potential long-term consequences of these injuries. Furthermore, this paper addresses how concussion history can inform clinical and return-to-play decisions. Recent studies incorporating novel brain imaging and electrophysiological technology for assessing residual impairment from multiple concussions are reviewed and the clinical implications of this work are discussed.
