Analysis of cognitive function trajectories and influencing factors in elderly patients with ischemic stroke: a prospective longitudinal study.
Article in Frontiers in aging neuroscience, 2026. 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 and purpose: Accurately defining cognitive function trajectories in elderly ischemic stroke patients is crucial for identifying high-risk groups for cognitive decline, enabling timely personalized interventions to improve long-term outcomes and reduce familial and societal burdens. However, research on the heterogeneity of cognitive trajectories and their underlying causes in elderly Chinese patients with ischemic stroke remains limited. This prospective longitudinal study aimed to detect unique trends in cognitive trajectories among these patients and assess the contributing factors. Methods: Validated assessment tools were utilized to systematically evaluate cognitive function at various specified intervals. Latent variable growth models were employed to delineate distinct subgroups of cognitive trajectories and to assess the predictive relevance of baseline pathophysiological markers and influencing factors in distinguishing these trajectories. Results: Cognitive trajectories were categorized into three latent groups: the High Cognitive Function-Slow Decline Group (51%), the Low Cognitive Function-Intermediate Decline Group (34%), and the Low Cognitive Function-Rapid Decline Group (15%). Logistic regression analysis revealed that age, temporal lobe infarction, serum homocysteine levels, National Institutes of Health Stroke Scale score, and Multidimensional Perceived Social Support Scale score, were significant predictors of cognitive function ( Conclusion: Geriatric patients with ischemic stroke have a gradual decline in cognitive function over time. Cognitive change trajectories can be categorized into three latent groups: High Cognitive Function-Slow Decline Group, Low Cognitive Function-Intermediate Decline Group, and Low Cognitive Function-Rapid Decline Group. Healthcare practitioners can develop tailored intervention strategies based on individual patients' cognitive trajectories and influencing factors to reduce cognitive decline and improve quality of life.
