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 a 64-year-old woman who developed symptomatic vasospasm on postoperative day 7 after clipping of an unruptured right middle cerebral artery (MCA) aneurysm. Imaging revealed right MCA vasospasm, which resolved with oral antiplatelets and intravenous vasodilators. She was discharged without neurological deficits. Although a few reports describe vasospasm after clipping unruptured aneurysms, this is the first to detail the clinical course, radiological findings, and treatment response. Potential risk factors include female sex, age 40-60, smoking, trigeminal neuralgia, and complex aneurysms. This case underscores the need to consider vasospasm even without subarachnoid hemorrhage for timely intervention.
