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

backgroundVertebrobasilar dolichoectasia (VBDE) is an uncommon cause of trigeminal neuralgia (TN), in which an ectatic vertebral artery (VA) compresses the root entry zone (REZ), while perforators may limit safe transposition.

methodsFully endoscopic microvascular decompression with VA transposition was performed. Preservation of all arterial branches was achieved and confirmed endoscopically.

conclusionIn VBDE-related TN, VA transposition may be the preferred decompressive strategy because of the characteristics of the ectatic vessel. Endoscopy offers a wide-angle view of the REZ, facilitating safe mobilization under full visualization of branch vessels.
