Association of serum albumin levels with multidomain functional impairment (motor, balance, ADL, and cognitive impairment) in Chinese post-stroke patients: a multicenter cross-sectional study.
Article in Frontiers in neurology. 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: Malnutrition, frequently indicated by hypoalbuminemia, is prevalent post-stroke and associated with adverse functional outcomes. However, the independent role of serum albumin (ALB) in multidomain functional recovery-encompassing motor, balance, cognitive, and daily living domains-remains underexplored in Chinese populations. This multicenter study aimed to quantify the independent association between serum ALB levels and functional impairment in Chinese post-stroke patients. Methods: In this cross-sectional study, 1,741 patients from rehabilitation centers across China were enrolled. ALB levels were categorized into quartiles (Q1: <37.7 g/L; Q2: 37.7-40.0 g/L; Q3: 40.0-42.8 g/L; Q4: ≥42.8 g/L). Outcomes included motor function (Fugl-Meyer Assessment), activities of daily living (Modified Barthel Index), balance (Berg Balance Scale), and cognition (Montreal Cognitive Assessment). Multivariable linear regression models adjusted for demographics, comorbidities, lesion characteristics, and illness duration. Subgroup analyses tested interactions by age, sex, BMI, and lesion topography. Results: Each 1-g/L ALB increase independently predicted functional gains: FMA ( Conclusion: ALB levels are independently and dose-dependently associated with motor, ADL, balance, and cognitive function in post-stroke patients. Compared to lower quartiles, patients with ALB ≥42.8 g/L (highest quartile) exhibit superior functional outcomes. A sex-specific pattern is observed solely in motor function, where the correlation is more pronounced in females. ALB may serve as a biological indicator for risk stratification during stroke rehabilitation.
