Predictors of futile recanalization following endovascular therapy for acute anterior circulation large vessel occlusion stroke: a retrospective cohort study.

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: Endovascular therapy (EVT) is effective for acute anterior circulation large vessel occlusion (LVO), yet futile recanalization remains common. Identifying its predictors is essential to optimize patient selection. Methods: This retrospective cohort study included 311 patients with anterior circulation LVO who underwent successful EVT. Patients were divided into an effective recanalization group (90-day modified Rankin Scale (mRS) score ≤ 2, Results: Baseline comparisons between the two groups showed significant differences in age, sex, atrial fibrillation, stress hyperglycemia ratio (SHR), C-reactive protein, admission National Institutes of Health Stroke Scale (NIHSS) score, diffusion-weighted imaging (DWI) infarct volume, DWI-Alberta Stroke Program Early CT Score (DWI-ASPECTS) score, number of procedure attempts, and procedure time. Univariate logistic regression and multivariate logistic regression identified admission NIHSS score (OR = 1.381, 95% CI: 1.113-1.713, Conclusion: Admission NIHSS score, SHR, DWI infarct volume, DWI-ASPECT score, and procedure time are independent predictors of futile recanalization after EVT for anterior circulation LVO stroke. Higher NIHSS score, elevated SHR, larger infarct volume, lower DWI-ASPECT score, and prolonged procedure time increase the risk of poor functional outcome despite successful reperfusion.
