Angiographic characteristics of ruptured versus unruptured vertebral artery dissecting aneurysm.

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.
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
objectiveVertebral artery dissecting aneurysm (VADA) is a rare and critical disease. VADA rupture can cause subarachnoid hemorrhage which is a major complication of VADA due to their high rebleeding rate and poor outcome. In the present study, ruptured and unruptured VADAs were compared by analyzing angiographic findings to determine useful predisposing factors for VADA rupture for appropriate treatment selection.
methodsSubjects with VADA treated during a 10-year period were retrospectively identified. The 57 cases diagnosed with VADA were divided into ruptured (n=15) and unruptured (n=42) groups. In addition, each case was analyzed using angiographic 3-dimensional (3-D) reconstructed images. Factors such as length, dilated and stenotic diameter, shape, and vessel around the vertebral artery (VA) were measured and statistically compared.
resultsIn the ruptured group, stenotic findings of the affected lesion were more common and severe than in the unruptured group. The average stenotic diameter was 2.27 mm (vs. 2.84 mm). And stenotic degree was 62% and 53% in the ruptured and unruptured groups, respectively. Posterior communicating artery (PcomA) flow was more common in the ruptured group (87% vs. 55%, p=0.028). Conclusions: Based on angiographic findings, stenotic lesions, which may be influenced by PcomA flow, are more common in ruptured VADAs.
