Running a risk? Sport supplement toxicity with ephedrine in an amateur marathon runner, with subsequent rhabdomyolysis.
Article in BMJ case reports, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
A 36-year-old man presented to the emergency department acutely unwell after being found collapsed while running a halfmarathon. He presented with a reduced Glasgow coma score, was tachycardic, agitated, hypoxic and profusely sweating. He had taken a 'supplement' given to him prior to the race by a friend, as he was concerned about not finishing. This contained both caffeine and a large dose of ephedrine (60 mg in total). After initial resuscitation he was intubated, and was transferred to critical care. He subsequently developed rhabdomyolysis, requiring haemofiltration.
