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 report on a case of a fulminant non-aneurysmal subarachnoid hemorrhage after COVID-19 in a patient without previous medical history or known previous illness despite a COVID-19 infection one month prior. We saw rarefied vessels in the area of the left middle cerebral artery besides a massive left frontal hemorrhage on cranial imaging. We concluded that these rarefied vessels are the expression of an RCVS, which fits the history of progressive headaches for one month. The RCVS might be caused by the COVID-19 infection and is related to the hemorrhage. Unfortunately, due to preoperative entrapment, brain death occurred a few days later.
