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
Objective: To retrospectively evaluate the efficacy and security of Willis covered stent (WCS) deployment for complex vascular diseases of the internal carotid (ICA) and vertebral (VA) arteries. Methods: Retrospective analysis was performed on complex vascular disease patients (n=36) treated with WCSs at our center between March 2017 and December 2022, with a 3-36-months follow-up surveillance and digital subtraction angiography (DSA) examination. Results: The WCSs were successfully deployed in all the patients. The 36 included lesions were carotid-cavernous sinus fistulas (CCFs; n=10) (27.8%), complex saccular aneurysms (n=10) (27.8%), traumatic pseudoaneurysms (n=7) (19.4%), blood blister-like aneurysms (BBAs; n=5) (13.9%), and iatrogenic carotid or vertebral artery ruptures (n=4) (11.1%). The WCS was released at the communicating segment (n=2) (5.6%), the ophthalmic segment (n=3) (8.3%), the clinoid and cavernous segment (n=28) (77.8%), the petrous segment (n=2) (5.6%) of ICA and the V3 segment (n=1) (2.8%) of VA. Postoperative DSA showed complete lesion occlusion in 26 patients (72.2%) who were immediately treated with WCSs, and endoleaks occurred in 3 patients (8.3%) (endoleaks resolved postadjustment in 7 patients (19.4%)). In patients (n=3) (8.3%) treated with double stents at the break of the ICA, the endoleak remained in 1 CCF patient (2.8%) during the 3-month follow-up, and the residual shunt disappeared after the second stent system was placed 3 months later. No aneurysm, bleeding or infarct recurrence reported, and only 1 patient (2.8%) had mild asymptomatic in-stent stenosis. Deaths and procedural complications did not occur during follow-up. Conclusion: Treatment with a WCS for intracranial complex vascular diseases resulted in satisfactory clinical outcomes and appeared effective and safe. Controlled, multicenter, large sample sizes and longer follow-up periods studies are necessary.
