Risk factors for surgery-related cerebral infarction after aneurysmal subarachnoid hemorrhage.
Article in Neurosurgical review, 2025. 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
Surgery-related cerebral infarction (SRCI) is an important complication after aneurysmal subarachnoid hemorrhage (aSAH), and detailed assessment of the characteristics and risk of SRCI is insufficient. We aimed to analyze the risk factors for SRCI in different treatment modalities after aSAH. A total of 472 patients were included in this retrospective study, including 169 in clip and 303 in endovascular. Regarding radiologically observable SRCI as the outcome, we used univariate and multivariate statistical analyses of risk factors and summarized the characteristics of SRCI. The incidence of SRCI was significantly higher in the clipping group compared to the endovascular group (47% vs. 21%, p < 0.001). Patients with SRCI in clip group had higher HH (p = 0.007) and mFisher (p = 0.007) and more diabetics (p = 0.018). They were more likely to receive primary EVD (p < 0.001), decompressive craniectomy (p = 0.022), multiple aneurysms repair (p = 0.008), and had longer procedure time (p = 0.006). Patients with SRCI in endovascular group were older (p = 0.001), more hypertensive (p = 0.001), with higher HH (p = 0.034) and longer procedure time (p = 0.005). They were more likely to presented with acute hydrocephalus (p = 0.030), type-3 aortic arch in pathway (p = 0.009) and proximal stenosis of the parent artery (p = 0.045). Multivariate regression analysis identified diabetes (OR = 7.050, 95%CI: 1.303-38.158), primary EVD (OR = 4.066, 95%CI: 1.567-10.550), longer procedure time (OR = 1.007, 95%CI: 1.001-1.013), and repair multiple aneurysms (OR = 3.916, 95%CI: 1.142-13.432) independently predicted SRCI in clip group. Age (OR = 1.033, 95%CI: 1.001-1.066), hypertension (OR = 2.337, 95%CI: 1.220-4.478), type-3 aortic arch in pathway (OR = 4.010, 95%CI: 1.177-13.666), and proximal stenosis of parent artery (OR = 2.442, 95%CI: 1.015-5.875) independently predicted SRCI in endovascular group. Diabetes, primary EVD, longer procedure time, and repair multiple aneurysms were independent risk factors for SRCI in clip group. In contrast, age, hypertension, type-3 aortic arch in pathway, and proximal stenosis of parent artery were independent risk factors for SRCI in endovascular group.
