Prevalence of basilar artery dolichoectasia in patients with acute ischemic stroke or transient ischemic attack in a single center of Spain.
Article in Revista de neurologia, 2024. 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
introductionBasilar artery dolichoectasia (BADE) refers to abnormal enlargement or displacement of the basilar artery (BA). The previously reported prevalence of BADE among patients with stroke is 0.3 to 33.1%, however, it might vary among studied populations. We aim is to determine the prevalence of BADE in patients presenting with acute ischemic stroke (AIS) or transient ischemic attack (TIA) in a Stroke Unit in a single center in Spain. PATIENTS AND
methodsPatients 50 years old or older presenting with AIS or TIA were eligible for inclusion. Demographic and clinical data were prospectively collected. Two neuroradiologists, blind to each other, assessed BA morphology.
resultsAmong 126 patients, 34.1% fulfilled the criteria for BADE (ectasia or dolichosis). BADE was associated with advanced age (p = 0.04). Patients with fetal-type circle of Willis presented smaller BA diameters (2.9 ± 0.1 vs. 3.5 ± 0.1; p < 0.001), whereas patients with lacunar strokes presented a greater diameter than other stroke subtypes (3.8 ± 0.3 mm vs. 3.3 ± 0.1 mm; p = 0.04). DISCUSSION AND
conclusionsIn this single-center study of patients presenting with AIS or TIA, the prevalence of BADE (ectasia or dolichosis) is high. Further studies focusing on Spaniards should confirm our results.
