Basilar Artery Diameter: Establishing a Reference Range for a Selected Black African Population.
Article in Ethiopian journal of health sciences, 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
Background: The basilar artery (BA) is a crucial vessel in the posterior cerebral circulation, supplying blood to the occipital lobes, cerebellum, and brainstem. Variations in BA diameter can be indicative of pathological conditions and may serve as a predictive marker for cerebrovascular events. Despite the importance of these measurements, data on the normal BA diameter in the Black African population is limited. This study aims to establish baseline values for BA diameter in healthy adults in Enugu, southeast Nigeria, and to examine any potential gender differences. Methods: A cross-sectional study was conducted on 298 subjects (150 males, 148 females) at the University of Nigeria Teaching Hospital Ituku/Ozalla, Enugu State. Participants, referred for brain CT, had normal radiologist reports. Contrast-enhanced brain CT scans were performed using a 64-slice Brilliance Philips scanner. BA diameter was measured on axial images at the midpons level. Results: The participants had a mean age of 49.4 years (±14 years). The BA diameter ranged from 3.1mm to 5.5mm, with a mean of 4.2mm (±0.5mm). Males had a significantly larger BA diameter compared to females (p<0.05). Diameter increased with age in both genders. Conclusions: This study provides reference values for BA diameter in a Nigerian population, highlighting a gender difference and age-related increase in diameter. These findings contribute to the understanding of BA geometry in Black Africans and can assist in diagnosing and managing cerebrovascular conditions.
