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

The treatment of carotid stenosis complicated by severe vessel tortuosity can present challenges in distal vessel selection and device delivery. This article reports the use of a steerable microcatheter (SM) for carotid artery stenting (CAS) in such cases. A 67-year-old male with transient lower extremity weakness and bilateral cerebral infarctions was found to have bilateral carotid stenosis. CAS was planned for both carotid arteries due to coronary artery disease. The left carotid artery exhibited severe stenosis with a 90-degree angle between the common and internal carotid artery (ICA). Anticipating difficulty in navigating the device, we used a 2.4 Fr SM. By adjusting the catheter tip to align with the ICA, we successfully guided the wire distally. Following the catheter exchange, a distal protection device was deployed, and CAS was completed successfully. SMs provide exceptional vascular selectivity and support, improving success in complex cases.
