Association between impaired brachial flow-mediated dilation and early neurological deterioration in acute ischemic stroke: a retrospective analysis.
Article in BMC neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundEarly neurological deterioration (END) occurs in individuals who had experienced acute ischemic stroke (AIS), impacting long-term functional outcomes. We aimed to investigate the association between endothelial function, measured via flow-mediated dilation (FMD), and END in patients with AIS.
methodsWe retrospectively reviewed patients who had experienced AIS within 7 days of stroke onset and underwent FMD assessments during their hospitalization (%FMD = Peak diameter - baseline diameter)/baseline diameter x 100). END was defined as ≥ 2-point increase in the National Institutes of Health Stroke Scale total score or ≥ 1-point increase in the motor score within 72 h post-stroke. Through multivariate analysis, we examined factors associated with END and explored the relationship between FMD and END with considering stroke mechanisms.
resultsAmong 1,262 patients diagnosed with AIS, 184 (14.6%) experienced END. Those with END were on average older (69 ± 13 vs. 67 ± 13 years; P = 0.033), had a higher prevalence of stroke history (21.2 vs. 12.9%; P = 0.003), and lower FMD (5.0 ± 1.8 vs. 5.4 ± 2.2%; P = 0.029). Multivariate analysis revealed that a history of stroke (adjusted odds ratio [aOR] = 1.728; 95% confidence interval [CI] 1.159-2.578; P = 0.007) and low % were independently associated with END. Subgroup analysis revealed that low %FMD was significantly associated with END within the small vessel disease (SVD) category (aOR = 0.789; 95% CI 0.679-0.920; P = 0.002).
conclusionsImpaired FMD may be associated with END, particularly within the context of SVD.
