Impact of Corticospinal Tract Involvement Beyond ASPECTS on Brain Imaging Prior to Endovascular Therapy in Patients with Large Ischemic Core.
Article in Stroke (Hoboken, N.J.), 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
backgroundThe Alberta Stroke Program Early Computed Tomography Score and core volume on preoperative imaging are key predictors of clinical outcomes following endovascular therapy in patients with a large ischemic core. Although the corticospinal tract is essential for motor function, its prognostic impact in patients with a large ischemic core remains unclear.
methodsThis multicenter retrospective study analyzed preoperative imaging data from patients with Alberta Stroke Program Early Computed Tomography Score ≤5 who underwent endovascular therapy. The presence of lesions in the posterior corona radiata and lesions in the primary motor cortex was assessed. A good outcome was defined as a modified Rankin Scale score ≤3 at 90 days. The association between lesions in the posterior corona radiata, lesions in the primary motor cortex, and good outcome was analyzed using univariable and stepwise multivariable logistic regression, with variable selection based on Akaike information criterion corrected for small sample size.
resultsAmong 107 patients, 37 (34.6%) achieved a good outcome. In univariable analysis, neither lesions in the posterior corona radiata nor core volume was significantly associated with a good outcome. In stepwise multivariable logistic regression, modified Rankin Scale score before onset (odds ratio, 0.30 [95% CI, 0.10-0.73]), cardioembolism (odds ratio, 0.25 [95% CI, 0.08-0.76]), absence of lesions in the primary motor cortex involvement (odds ratio, 13.49 [95% CI, 3.75-63.45]), and shorter onset-to-reperfusion time (odds ratio, 0.996 [95% CI, 0.992-0.998]) were independent predictors. Alberta Stroke Program Early Computed Tomography Score and the absence of multiple artery occlusion were retained in the final model but were not statistically significant.
conclusionAbsence of lesions in the primary motor cortex involvement was independently associated with good outcome after endovascular therapy in patients with large ischemic core, suggesting its potential utility as a complementary imaging marker in this population.
