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

This case report follows a 60-year-old female with a history of hypertension, diabetes, and Factor V Leiden mutation with multiple prior deep vein thromboses (DVT) in the lower extremities who presented with right eye vision loss. Computed tomography angiogram (CTA) of the neck showed a 4 vessel arch anatomy with an absence of the left common carotid artery and separate origins of the left internal and external carotid arteries directly arising from the arch, which was an incidental finding. This case contributes to the sparse existing literature and highlights the extremely rare occurrence of complete carotid artery agenesis and its clinical implications.
