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 48-year-old man had convulsions, and magnetic resonance angiography (MRA) showed diffuse constriction of the cerebral arteries. He was suspected of having primary angiitis of the central nervous system (PACNS) and treated with steroid for three days. The MRA abnormality disappeared after a week. After 69 days, he developed dizziness, and MRA revealed recurrence of cerebral artery stenosis. Nevertheless, the symptoms and abnormal MRA findings recovered promptly without treatment. He was diagnosed with reversible cerebral vasoconstriction syndrome (RCVS) without headache. This case suggests that RCVS should be a differential diagnosis in patients without headache whose MRA findings show multiple cerebral artery stenosis.
