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

In this case series, we aimed to evaluate the ultrasonic characteristics of 35 patients with persistent carotid-vertebrobasilar anastomoses (PCVBA), a rare variant between the anterior and posterior cerebral circulation. Ultrasound detected seven (30.4%, 7/23) primitive trigeminal arteries (PTA), eight (100%, 8/8) primitive hypoglossal arteries (PHA), and four (100%, 4/4) proatlantal intersegmental arteries (PIA). PHA and PIA can be observed as abnormal branches arising from the internal or external carotid artery, most likely accompanied by hypoplastic vertebral arteries with low velocities and high resistances. Still, the basilar arteries had normal blood flows in stark contrast to the vertebral arteries.
