Outcomes of Endovascular Treatment for Acute Basilar Artery Occlusion With National Institutes of Health Stroke Scale Score ≤10.
Article in Journal of the American Heart Association, 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
backgroundThe effectiveness and safety of endovascular treatment (EVT) compared with standard medical treatment (SMT) for acute basilar artery occlusion in patients with National Institutes of Health Stroke Scale (NIHSS) scores ≤10 remain unclear. This study aimed to investigate the effectiveness and safety of EVT versus SMT in patients with acute basilar artery occlusion with NIHSS scores ≤10.
methodsPatients with acute basilar artery occlusion and NIHSS scores ≤10 included in this study were derived from a nationwide prospective registry in China. Patients were divided into the EVT and SMT groups. The primary outcome was the distribution of modified Rankin Scale score at 90 days. Safety outcomes included death at 90 days and symptomatic intracerebral hemorrhage within 48 hours.
resultsAmong 106 patients, 78 (73.6%) received EVT. The median age was 64 (interquartile range, 59-71) years, and 23 (21.7%) were women. Compared with SMT, EVT was associated with a favorable shift in the distribution of modified Rankin Scale score at 90 days (adjusted odds ratio, 6.22 [95% CI, 2.31-16.73]) and lower 90-day death (adjusted odds ratio, 0.23 [95% CI, 0.06-0.88]). There was no significant difference in the incidence of symptomatic intracerebral hemorrhage within 48 hours between the 2 groups. At 1-year follow-up, functional outcomes continued to favor EVT over SMT. In both groups, as the baseline NIHSS score increased, the probability of achieving favorable outcomes progressively decreased, while the probability of death increased.
conclusionsIn patients with acute basilar artery occlusion and NIHSS scores of ≤10, EVT was associated with better functional outcomes and lower mortality rate.
