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

backgroundEagle syndrome, or elongated styloid process syndrome, is a rare cause of cerebral infarction. When the styloid process is elongated but the internal carotid artery (ICA) is morphologically normal on three-dimensional computed tomography angiography (3D-CTA), determining the causal relationship between elongation and cerebral infarction is difficult. OBSERVATIONS: The patient was a 27-year-old man who experienced two left cerebral infarctions in 3 months. On 3D-CTA, the styloid process was elongated, but the structure of the ICA was normal. When the patient's neck was rotated leftward, the peak systolic velocity and pulsatility index increased (shown via dynamic subtraction ultrasonography) and ICA stenosis was evident (shown via subtraction angiography). The styloid process was removed, and the cerebral infarction did not recur in the 2 years after surgery. LESSONS: This is the first report to document that indirect compression of ICA by the styloid process can cause Eagle syndrome. The blood flow changes of the ICA on dynamic ultrasonography revealed morphological changes that were hidden on 3D-CTA or nondynamic subtraction angiography.
