Predictors of Futile Recanalization in Patients With Basilar Artery Occlusion With Large Versus Nonlarge Infarcts.
Article in Journal of the American Heart Association, 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
backgroundBasilar artery occlusion is associated with high rates of disability and mortality, and despite advances in endovascular treatment, futile recanalization remains a challenge. This study aims to identify predictors of futile recanalization in patients with basilar artery occlusion, focusing on large and nonlarge infarcts. METHODS AND
resultsThis multicenter retrospective study included patients from 65 centers across China. Patients were categorized based on posterior circulation Alberta Stroke Program Early CT [Computed Tomography] Score (pc-ASPECTS) into 2 groups: large infarcts (pc-ASPECTS ≤6) and nonlarge infarcts (pc-ASPECTS >6). Predictors of futile recanalization-defined as a modified Rankin Scale score of 4 to 6 at 90 days despite successful recanalization-were analyzed using logistic regression models. Among the 2075 patients, 1113 (53.6%) experienced futile recanalization. In patients with pc-ASPECTS >6, predictors of futile recanalization included older age (odds ratio [OR], 1.18 [95% CI, 1.06-1.31]), higher National Institute of Health Stroke Scale scores (OR, 1.75 [95% CI, 1.58-1.94]), and prolonged time from puncture to reperfusion (OR, 1.24 [95% CI, [1.12-1.38]). Intravenous thrombolysis (OR, 0.85 [95% CI, [0.77-0.94]) and achieving modified Thrombolysis in Cerebral Infarction grade 3 (OR, 0.81 [95% CI, [0.74-0.90]) were associated with a lower likelihood of futile recanalization. In patients with pc-ASPECTS ≤6, being male (OR, 0.75 [95% CI, 0.58-0.96]) and having higher pc-ASPECTS scores (OR, 0.65 [95% CI, 0.48-0.85]) were protective against futile recanalization, whereas higher National Institute of Health Stroke Scale scores increased the risk (OR, 1.81 [95% CI, 1.42-2.32]).
conclusionsThis study identifies distinct predictors of futile recanalization in patients with basilar artery occlusion based on infarct size. The findings underscore the importance of individualized treatment strategies and timely intervention to optimize endovascular treatment outcomes in high-risk patients.
