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

Anomalies of the vertebral arteries are rare. The second most common vertebral artery anomaly is the right vertebral artery arising from the right common carotid artery in the setting of an aberrant right subclavian artery (ARSA). We present a case of this rare anomaly and determine the relative frequency with which the right vertebral artery arises from the right subclavian artery vs the right common carotid artery in the setting of an ARSA by retrospectively reviewing over 500 patients with an ARSA and a contrast-enhanced CT. We found that in the setting of an ARSA the right vertebral artery arises from the right subclavian artery in 84% of patients and from the right common carotid artery in 16% of patients.
