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

backgroundThe atlantoaxial and intracranial segments of vertebral artery (V(3-4)) are winding around their peripheral structures. Their panorama is not easy to be observed in surgery. CT angiography (CTA) shows some advantages in this aspect. So, the aim of this study is to reveal the three-dimensional (3D) anatomy related to V(3-4) and prepare ground for clinical diagnosis and treatment.

methodsNinety-eight cases without the pathologies of V(3-4) were selected from the head-neck CTA examination. All the 3D images were formed with multiplanar reconstruction, volume rendering and volume rendering together with separating, fusing, opacifying and false-coloring. On the 3D images, the courses and branch of V(3-4) were observed and measured, as well as their peripheral venous vascular plexus (VVP).

resultsV(3-4) with typical five curves was found in 85 cases and with variations in 13. The left V(3-4) is larger than right (P < 0.05). The branch shown on the 3D image is the posterior inferior cerebellar artery at V(4), at most two on either side. VVP are at the back of the atlantoaxial joints and around the V(3), each on either side. There is no significant difference in size and shape between left and right (P > 0.05).

conclusionsThe anatomy and variations of V(3-4) can be clearly and directly shown by 3DCTA. The understanding of vertebral artery and bony structures around there can provide anatomic basis for surgery and radiological diagnosis.
