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 evaluate the safety and efficacy of employing LEO stents in dual stent-assisted embolization (DSAE) for wide-necked intracranial bifurcation aneurysms, and to assess the effectiveness of combined IA and IV intra-procedural infusion of tirofiban in mitigating perioperative complications. Methods: Clinical data and follow-up images from 562 patients with wide-necked intracranial bifurcation aneurysms treated at First Affiliated Hospital of Army Medical University from 2018-2022 were collected. Among them, 65 received DSAE with LEO stents. The study observed treatment success rates, procedure-related complications, perioperative thromboembolic events (TEs) and hemorrhagic events (HEs), immediate postoperative modified Raymond-Roy classification (mRR), and follow-up imaging. Glasgow Outcome Scale (GOS) at discharge and clinical follow-ups were recorded. Results: The study enrolled 65 patients (mean age: 56.77 ± 10.07) with wide-necked intracranial bifurcation aneurysms. Among them, 58 had unruptured aneurysms, 7 ruptured (Hunt-Hess II-III). All aneurysms were successfully embolized without significant stent or bleeding complications. Only one case had intraoprative thrombosis; two postoperative ischemic incidents occurred within three days, no severe bleeding events. Immediate imaging showed modified Raymond-Roy classification: mRRC I (92.3%), mRRC II (4.6%), mRRC III b (3.1%). A total of 43 patients were followed up postoperatively with DSA. Among them, 41 patients exhibited mRRC I, while 2 patients exhibited mRRC II. No aneurysm was recanalized. Discharge GOS: GOS 5-60, GOS 4-1, GOS 3-4. One patient, GOS 1, died from lung cancer; others improved. Conclusion: The utilization of LEO stents for dual stent-assisted embolization of wide-necked intracranial bifurcation aneurysms demonstrated remarkable success and safety, yielding favorable postoperative outcomes and no instances of aneurysm recurrence. The concomitant administration of perioperative antiplatelet medications alongside IA and IV intra-procedural infusion of tirofiban effectively attenuated thromboembolic events (TEs) without concomitant elevations in bleeding risks.
