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

Spontaneous thrombosis of intracranial aneurysms is rare. Spontaneous regression of unruptured small saccular aneurysms is even more rare. A 76-year-old woman with a history of hypertension and dyslipidemia was referred for evaluation of an unruptured intracranial aneurysm. Magnetic resonance angiography showed a left internal carotid artery aneurysm with a maximum width of 4.0 mm and a neck diameter of 3.0 mm. She was monitored using annual magnetic resonance angiography. Imaging at the 8.5-year follow-up showed partial aneurysm regression and stenosis in the parent artery proximal to the aneurysm. The next year, it had almost completely regressed. Spontaneous regression can occur even with unruptured small intracranial aneurysms. In our patient, proximal parent artery stenosis may have played a role.
