Caregiver Psychosocial Factors & Stroke Survivor Cognitive Outcomes: A REGARDS-CARES Cohort Study.
Article in International journal of geriatric psychiatry, 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
objectivesCaring for an individual with cognitive impairment carries a physical, mental, and emotional toll. This manuscript examines the relationship between caregiver psychosocial measures and longitudinal cognitive outcomes of stroke survivors, as well as analyzing the psychosocial factors as moderators of stroke severity and cognition.
methodsThis analysis was conducted on caregiver and stroke survivor dyads (n = 157) that participated in the Caring for Adults Recovering from the Effects of Stroke (CARES) project, an ancillary study of the REasons for Geographic and Racial Differences in Stroke (REGARDS) national cohort study. Stroke severity at hospitalization discharge was included as the primary predictor of cognitive outcomes and caregiver psychosocial factors were included as additional predictors. Cognition was assessed biennially and measured the domains of learning, memory, and executive functioning. Individual mixed-effect models included each psychosocial factor and were covariate-adjusted for pre-stroke cognitive scores and demographic variables. Caregiver psychosocial factors included caregiver strain, depressive symptoms, life and leisure time satisfaction, and overall quality of life.
resultsDecreased caregiver strain (b = -0.230, 95% CI: -0.39 to -0.07; p = 0.006) and increased leisure time satisfaction (b = 0.045, 95% CI: 0.01 to 0.08; p = 0.005) were both found to be significant predictors, alongside stroke severity (b = -0.137, 95% CI: -0.22 to -0.05; p = 0.002), of better stroke survivor cognition overall. No variables were found to be moderating factors of the relationship between stroke severity and cognition.
conclusionsUnderstanding the caregiver psychosocial factors that predict stroke outcomes will help clinicians to identify stroke survivor and caregiver dyads at higher risk for worst longitudinal cognitive outcomes following stroke.
