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

aimThe aim of our study was to demonstrate some possible variations in the vertebrobasilar system (VBS) in the Turkish population and to compare our results with the literature. MATERIALS AND

methodsThe VBS samples were taken from 109 fresh forensic autopsies and one anatomic cadaver. The widths of the vertebral artery (VA), the basilar artery (BA) and their branches were measured; dominancy and hypoplastic arteries, as well as the types of variations and their locations, were determined.

resultsHypoplastic VA was observed at rates of 20.2% on the right, 14.4% on the left and 4.8% bilaterally. The vertebrobasilar junction was found to be either at the level of bulbopontine sulcus (20%), below the sulcus (67%) or above the sulcus (12%). BA variations were observed as duplications of the proximal (0.9%) and distal segments (1.8%). Anterior spinal artery (ASA) originated as a single trunk in 12.5% of the cases. ASA arose from a transverse anastomosis connecting VAs in 6.3% of the cases. Furthermore, 15.6% of ASAs were double. The observed variations in the superior cerebellar artery were early bifurcation (7.2% on the right, 12.7% on the left), fenestration (4.5% on the right, 7.2% on the left), duplication (14.5% on the right, 12.7% on the left) and origin as a common trunk (6.3% on the right, 10% on the left).

conclusionOur results show that a high percentage of variations can be seen even in a small number of cases. We believe that our data are clinically important because, for example, variations are a factor which increases the incidence of aneurism and thrombus. We also think our results will contribute to the demography of our country and to clinical medicine.
