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
backgroundSarcopenic obesity (SO) is characterized by the coexistence of sarcopenia and obesity, associated with adverse health outcomes. This study aimed to investigate the prevalence of SO as defined by the recently published Japanese Working Group on Sarcopenic Obesity (JWGSO) criteria in post-stroke patients undergoing rehabilitation and its association with activities of daily living (ADL) and length of hospital stay.
methodsThis retrospective cohort study analyzed stroke patients aged 40-75 years undergoing rehabilitation. SO was diagnosed using JWGSO criteria. The primary outcome was the Functional Independence Measure (FIM) motor score at discharge, with length of hospital stay as a secondary outcome. Multiple linear regression analysis was performed to assess associations between SO and outcomes.
resultsThe study included 405 patients with a median age of 65 years (interquartile range, 58-71), of whom 60.7% were male. The prevalence of JWGSO-defined SO was 5.4%. Multivariate regression analysis revealed no significant association between JWGSO-defined SO and FIM-motor at discharge (β=0.015, p=0.664) or length of stay (β=0.008, p=0.828). Sarcopenia alone demonstrated significant negative associations with both outcomes.
conclusionThe prevalence of JWGSO-defined SO in post-stroke rehabilitation patients was 5.4%, with no significant association with ADL or length of hospital stay. Sarcopenia alone showed stronger associations with outcomes, suggesting the importance of addressing muscle mass and strength in stroke rehabilitation.
