Risk Factors and Predictive Model for Ischemic Complications in Endovascular Treatment of Intracranial Aneurysms: Insights From a Large Patient Cohort.
Article in Aging medicine (Milton (N.S.W)), 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
Objectives: There remains a conspicuous absence of systematic analysis concerning the risk factors for the development of ischemic complications in the interventional treatment of IAs. Our study aimed to identify the risk factors for ischemic complications after the interventional treatment of IAs and to make an individualized prediction of the occurrence of ischemic complications, providing important reference guidance for clinicians. Methods: This study encompassed a sample of 473 patients diagnosed with intracranial aneurysms (IA) and treated at our center between February 2022 and April 2024. Ischemic complications were identified via clinical symptomatology and corroborated with diagnostic subtraction angiography (DSA), computed tomography (CT), or magnetic resonance imaging (MRI). We used a machine learning (ML) approach to screen potential variables for ischemic complications and identify correlations between them, and subsequently constructed a logistic regression model to quantify these correlations. Results: Patients were categorized based on the occurrence or absence of ischemic complications. A total of five potential factors were screened using LASSO regression, XGBoost, and Randomforest algorithms: hypertension, history of alcohol consumption, multiple IAs, rupture status, and antiplatelet agent. Multivariate analysis further disclosed that hypertension, history of alcohol consumption, ruptured aneurysms, and antiplatelet agent were independent risk factors for postoperative ischemic complications. The predictive model, derived from the multivariate regression analysis results, demonstrated robust reliability. Conclusions: Hypertension, history of alcohol consumption, ruptured aneurysms, and antiplatelet agent as independent risk factors for ischemic complications following the interventional treatment of IAs. Accordingly, we constructed the first risk prediction model regarding ischemic complications of all IAs based on these factors, aiming to enhance prognostic judgment and treatment strategy planning.
