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

We herein report a case of reversible cerebral vasoconstriction syndrome (RCVS) with an unusual presentation of hyperdense blood vessels. A 53-year-old woman developed thunderclap headache. Brain computed tomography (CT) showed hyperdensity of the anterior cerebral artery. Brain magnetic resonance imaging revealed cerebral infarctions in the left anterior cerebral artery (ACA) territory and cerebellum. The left ACA presented with a hyperintense vessel sign, although magnetic resonance angiography (MRA) appeared normal. One week later, stenotic changes were confirmed using MRA. The vasoconstriction disappeared on day 20, and the patient was diagnosed with RCVS. CT-defined hyperdense vessel signs can be observed at an early stage of RCVS, leading to ischemic events.
