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

Data on the use of Woven EndoBridge (WEB) devices in the treatment of narrow-neck intracranial aneurysms (NNA) are limited. We compared the efficacy and safety of single-layer (SL) and single-layer spherical (SLS) WEB devices in treating NNA. We conducted a multicenter retrospective analysis of adult patients with NNA (neck ≤ 4 mm and width-to-neck ratio ≥ 2) treated with SL or SLS WEB devices between January 2011 and December 2022. Patients with fusiform or blister aneurysms, adjunctive treatments, or devices other than SL or SLS were excluded. Propensity score matching was used to adjust for confounding variables. Outcomes included procedural complications, angiographic occlusion rates using the Raymond Roy classification, major device compaction, need for retreatment, and functional outcomes assessed by the modified Rankin Scale (mRS). After matching, resulting in 101 patients in each group, baseline characteristics were well-balanced. Thromboembolic complications occurred in 2.0% of the SLS group and 5.9% of the SL group (P = 0.28). Hemorrhagic complications occurred in 1.0% of the SLS group and 6.4% of the SL group (P = 0.062). Adequate occlusion rates (Raymond Roy grades I and II) were similar between groups (96% in SLS vs. 91% in SL; P = 0.20). Major device compaction was significantly less frequent in the SLS group compared to the SL group (0% vs. 7.6%; P = 0.024). The need for retreatment trended to be lower in the SLS group (1.1% vs. 6.6% in SL; P = 0.12). Functional outcomes (mRS 0–1) at last follow-up were comparable (82% in SLS vs. 86% in SL; P = 0.41). In the treatment of narrow-neck intracranial aneurysms, the SLS WEB device was associated with significantly lower rates of major device compaction compared to the SL device. Reduced compaction may lead to a lower need for retreatment. Overall imaging outcomes and safety profiles were similar between the two devices.
