Endovascular treatment versus best medical treatment for acute anterior cerebral artery occlusion: a single-center inverse probability of treatment-weighted cohort study.
Article in Frontiers in neurology, 2026. 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
Introduction: Evidence regarding the benefit of endovascular treatment (EVT) for isolated acute anterior cerebral artery occlusion remains limited. We aimed to compare the efficacy and safety of EVT versus best medical treatment (BMT) in this population. Methods: We retrospectively screened consecutive patients with acute anterior cerebral artery occlusion between May 2020 and October 2025. The primary outcome was excellent functional outcome, defined as a 90-day modified Rankin Scale (mRS) score of 0-1. Secondary outcomes included 90-day mRS 0-2, mRS 0-3, mortality, symptomatic intracranial hemorrhage (sICH), and any intracranial hemorrhage (any ICH). Multivariable logistic regression and inverse probability of treatment weighting (IPTW) were used to adjust for baseline differences. Results: Among 69 included patients, 37 received BMT and 32 underwent EVT. Successful reperfusion was achieved in 27 of 32 patients treated with EVT (84.4%). The primary outcome of 90-day mRS 0-1 occurred in 17 of 37 patients (45.9%) in the BMT group and 13 of 32 patients (40.6%) in the EVT group. EVT was not significantly associated with 90-day mRS 0-1 after adjustment (adjusted odds ratio [OR], 1.74; 95% confidence interval [CI], 0.50-5.99). No significant differences were observed for 90-day mRS 0-2, mRS 0-3, mortality, sICH, or any ICH. IPTW-adjusted sensitivity analyses yielded consistent results. Conclusion: EVT showed high reperfusion success but was not associated with a statistically significant improvement in 90-day functional outcomes compared with BMT. Further multicenter studies are needed to clarify the potential role of EVT in this population.
