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

A 68-year-old man with symptoms of back and left anterior chest pain was diagnosed with non-ST-segment elevation myocardial infarction and underwent coronary angiography, which showed 99% stenosis in the diagonal artery. After administering dual antiplatelet therapy, the lesion was successfully treated with a drug-eluting stent. On the day following the procedure, he developed left upper extremity paresthesia with persistent back pain, which was diagnosed as spontaneous spinal epidural hematoma by magnetic resonance imaging. Urgent surgical decompression was performed, leading to a complete resolution of the neurological symptoms. This case describes the difficulties in making a diagnosis and the necessity of performing immediate management.
