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

Intracranial atherosclerotic disease (ICAD) is one of the most common causes of stroke worldwide and the one with the worst prognosis. In this study, we assessed the hypothesis that the balance of circulating pro- and antiangiogenic factors plays a role in the evolution of the disease and can be used as a potential marker for the disease course and a target for treatment. Seventy-four patients with severe ICAD were enrolled in this prospective observational study, medically optimized, and followed for 6 months. Thirteen pro- and eight antiangiogenic factors were measured in the participants' serum using a sandwich multiplex ELISA. Angiogenic profiles were calculated using principal component analysis. We tested the association between angiogenic profiles and recurring cerebrovascular events despite intensive medical therapy, disability at 6 months after enrollment, and angiographic neovascularization in patients who failed medical treatment and underwent indirect revascularization surgery. There is a strong association between a functionally antiangiogenic profile and recurrent stroke or TIA in patients with ICAD (OR = 7.2, CI 2.4-34.4). Multivariable regression analysis showed that this antiangiogenic profile was also associated with poor functional status after 6 months (p = 0.002), independent from other clinical features such as history of previous stroke, diabetes, and age. In patients who failed medical management and underwent indirect revascularization surgery, high endostatin and angiostatin levels were also associated with low angiographic neovascularization (p = 0.02). The results of this study point to the striking importance of antiangiogenesis as a determinant of ICAD patient prognosis and suggest a possible new target for therapy.
