Effectiveness and safety of the Sugita clip for ruptured and unruptured intracranial aneurysms: A retrospective cohort study.
Article in Surgical neurology international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: The long-term outcomes, adverse events, and occlusion rates of the Sugita clip remain unknown. This study evaluated the effectiveness and safety of the Sugita clip by assessing its outcomes and related complications. Methods: Patients who underwent cerebral aneurysm clipping for ruptured or unruptured cerebral aneurysms using the Sugita clip at Nagoya University Hospital and its affiliated facilities between January 01, 2016, and December 31, 2017, were enrolled. We retrospectively investigated patient background, operative information, intraoperative and perioperative complications, device malfunctions, occlusion and parent artery patency rates, and postoperative modified Rankin scale (mRS). We divided patients into two groups based on postoperative mRS to investigate factors that cause deterioration in neurological prognosis. Results: In total, 228 patients with unruptured intracranial aneurysms (UIAs) and 364 with ruptured intracranial aneurysms (RIAs) were included. Concerning postoperative mRS (91-365 days), 223 patients with UIAs and 258 with RIAs had good outcomes (mRS 0-2). Regarding device safety, there were no reports of aneurysm recurrence, parent artery occlusion due to clip slippage, foreign body reactions in the surrounding brain tissue, or device malfunctions. Factors that affected neurological outcomes in UIAs included perioperative hemorrhagic and ischemic complications. Contrastingly, in RIAs, age, Hunt and Kosnik grade, World Federation of Neurosurgical Societies (WFNS) grade, and perioperative ischemic complications were found to affect neurological prognosis. Conclusion: Postoperative mRS of patients who underwent aneurysm surgery using the Sugita clip was comparable to that of global treatment, with no device-related complications, supporting the effectiveness and safety of the Sugita clip.
