Quantitative volumetric and lesion length analysis for evaluating the severity of intracranial vertebrobasilar dolichoectasia.

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
Background: Vertebrobasilar dolichoectasia (VBD) is a rare disease, and the pathogenesis and factors associated with its prognosis are still unclear. Despite the high incidence of enlargement, rupture, and ischemia, the therapeutic indication and strategy of VBD remain unestablished. This study aimed to identify the factors associated with the outcome of VBD and to investigate its current treatment. Methods: We retrospectively reviewed patients who were diagnosed with VBD at 39 institutions in Japan between 2010 and 2019. Results: A total of 114 cases were collected, and 96 cases were included in the analysis. The median age of the patients was 65 years, the median follow-up was 2.7 years, and the median time from the initial diagnosis was 5.0 years. A total of 40.3% of patients had a modified Rankin Scale (mRS) scale of 0-2, and 42.3% of patients had a mRS score of 5-6. In a multivariate analysis, a shorter lesion length ( Conclusion: The lesion length and VB artery volume are independent factors associated with the outcome of VBD. The treatment of aneurysms is still challenging, and indications for treatment should be carefully determined.
