A Novel Technique for Mitigation of the Ledge Effect Caused by the Use of a Large-Lumen Catheter during Neurointervention: Beanstalk Method.
Article in Asian journal of neurosurgery. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Navigating a large-caliber catheter into the intracranial artery may generate a "ledge effect," which disturbs successful neurointervention. Particularly, navigation of a large-lumen aspiration catheter is often required to achieve fast recanalization in acute ischemic stroke cases. Occasionally, the aspirator cannot be passed through the ophthalmic artery origin because of the ledge effect. Here, we report a new technique for mitigation of the ledge effect that involves the use of double micro-guidewires (MGWs). We refer to this technique as the "beanstalk method." We evaluated the efficacy of our idea using a silicon vascular model. Two 0.014" MGWs are used for navigation of a 0.068" aspirator. After one guidewire is navigated to the distal portion, another MGW is advanced along with the former guidewire, in a spiral fashion, similar to the growth of a beanstalk. The aspirator can then pass with the coaxial double-guidewire, although there is a severe gap in the vessel. We performed an
