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: Endovascular therapy is the primary treatment modality for intracranial aneurysms (IA). The objective of this study was to assess the effectiveness and safety of a pipeline embolization device (PED) for the treatment of IA. Methods: This retrospective study was conducted at a single center. Data were collected for all patients who underwent PED treatment at the Fourth Affiliated Hospital of Xinjiang Medical University between December 2018 and January 2022. Clinical characteristics, aneurysm-related characteristics, treatment details, and clinical and imaging outcomes were collected and analyzed. Results: A total of 60 consecutive patients with 60 IAs were treated with a PED. The mean age of the participants was 61.8 years, with 53% being female. The average size of the aneurysms was 14.7 mm, with 54 located in the anterior circulation and six in the posterior circulation. The median last follow-up time was 13.0 months (range, 11-24 months). All patients underwent final digital subtraction angiography (DSA) for angiographic follow-up, and 50 aneurysms (83.3%) were completely occluded. The overall complication rate was 3.3%, and there were no reported mortalities. Among the 12 cases of ruptured aneurysms, all of which underwent adjunctive coil embolization, the complete occlusion rate was 91.7% with a complication rate of 16.6% [ischemic complication and modified Rankin scale (mRS) deteriorated]. In the 6 cases of posterior circulation aneurysms (2 in the basilar artery), 5 cases achieved complete occlusion and 1 case achieved near-complete occlusion, with no reported complications or mortality. Conclusions: The use of PEDs appears to be an effective treatment option for IA, demonstrating high occlusion rates and low complication rates. While the application of PEDs for the treatment of ruptured aneurysms did not increase the risk of secondary aneurysm rupture, caution is still warranted due to a higher complication rate. In the treatment of aneurysms of the vertebrobasilar artery using PEDs, this study achieved favorable efficacy outcomes without complications nor patient mortality. However, further studies are needed to validate these findings.
