Impact of Stroke History on Cognitive Function, White Matter Hyperintensities, and Circulating BDNF Levels.
Article in Archives of Iranian medicine, 2025. 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 present study aims to investigate the impact of stroke history on cognitive function, white matter hyperintensities (WMHs), and circulating brain-derived neurotrophic factor (BDNF) levels in brain lesion patients.
methodsIn this study, we enrolled 228 individuals exhibiting clinical symptoms of stroke from the Golestan Cohort Study. The participants were categorized into two groups based on their stroke history. Subsequently, 120 patients with a history of stroke and 108 patients without obvious brain lesions were subjected to comparative analysis using magnetic resonance imaging (MRI). Montreal Cognitive Assessment (MoCA) and Fazekas scores were used to evaluate cognitive function and WMH burden, respectively. In addition, circulating BDNF levels were measured using the Human BDNF Elisa kit.
resultsTotally, 228 patients were recruited in the study with a mean age of 63.8 years. Stroke was found in 52.6%. MoCA scores and plasma BDNF levels were significantly lower in patients with a history of stroke compared to people without such a history after adjusting for age, sex, education and type of residency (adjusted regression coefficient (RC) (95% CI)=-4.0 (-5.0 to -3.0), -3.2 (-4.2 to -2.2), respectively). In addition, the intensity burden of white matter was higher in the stroke group (adjusted RC (95% CI)=1.2 (0.8 to 1.6).
conclusionThe study suggests that a multi-biomarker approach, encompassing measures such as the MoCA score, Fazekas score, and circulating BDNF levels, can provide valuable insight into the neurological status of post-stroke patients and highlight potential avenues for improving patient outcomes through early detection and intervention strategies.
