Body mass index and all-cause mortality in US stroke population: a cohort study.
Article in BMC neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundObesity and overweight are major global health concerns, associated with increased rates of stroke and mortality. This study sought to investigate the relationship between BMI and all-cause mortality among stroke patients in the United States.
methodsThis study utilized data from 1,603 stroke survivors from the National Health and Nutrition Examination Survey (NHANES) cycles (1999-2018) linked to the National Death Index. BMI was calculated and grouped into normal weight (BMI < 25 kg/m²), overweight (25 ≤ BMI < 30 kg/m²), or obese (BMI ≥ 30 kg/m²).
resultsHigher BMI was inversely related to all-cause mortality and therefore associated with lower mortality in overweight and obese patients than in individuals with normal weight (HR for 25 ≤ BMI < 30 kg/m
conclusionsStroke survivors with elevated BMI, particularly those categorized as overweight or obese, exhibit reduced all-cause mortality in comparison to individuals with normal or low BMI. Further investigation is necessary to clarify this paradox's mechanisms and improve clinical recommendations.
