Acute post-stroke cognitive test performance predicts one-year functional independence.
Article in medRxiv : the preprint server for health sciences, 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
Objective: General cognitive ability (g), a latent variable derived from cognitive data, can predict life outcomes (e.g., educational attainment and occupational success) among neurologically healthy individuals. The value of g for predicting post-stroke functional outcomes is unknown. We addressed this gap here. Method: We derived g using exploratory structural equation modeling of 15 neuropsychological tests administered to 112 patients with stroke, 69 of whom also had functional outcome data (42 men; mean age = 53.23 years (SD = 10.54)). We used logistic regressions to compare g and individual tests in terms of their ability to predict the Functional Assessment Measure (FAM) and the Functional Independence Measure (FIM; motor and cognitive subscales) at 12 months post-stroke. Results: g was a statistically significant predictor of FAM ( Conclusions: Acute measures of cognition, including g, can predict functional independence 12 months after stroke. g and visuospatial ability measures were the most robust predictors.
