Proportions, trends, and outcomes of posterior circulation ischemic stroke in the United States.
Article in Frontiers in neurology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Posterior circulation ischemic stroke has been previously studied in single-center and multicenter registries. The contemporary proportions, trends, and outcomes of posterior circulation ischemic stroke at a national level are not known. Methods: We identified patients admitted with ischemic stroke using the Nationwide Inpatient Sample from 2016 to 2022. We compared the rates of intravenous (IV) thrombolysis, thrombectomy, in-hospital mortality, routine discharge without palliative care (based on discharge disposition), and length and costs of hospitalization in patients admitted with posterior circulation ischemic stroke to patients admitted with anterior circulation ischemic stroke. Results: Among 4,773,715 ischemic stroke admissions, 1,675,030 (35.1%) had a territory-specific localization code and 1,630,520 were included for analysis. A total of 383,990 (23.6%) and 1,246,530 (76.4%) patients were admitted with posterior and anterior circulation ischemic stroke, respectively. From 2016 to 2022, the number of patients admitted with posterior circulation ischemic strokes increased from 42,055 in 2016 to 73,755 in 2022, demonstrating a temporal trend (p trend Conclusions: Over 20% of acute ischemic strokes occur in posterior circulation territories in the United States. Patients with posterior circulation ischemic stroke are less likely to receive acute stroke treatment compared with those with anterior circulation ischemic stroke.
