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
Objectives: This study investigated whether sarcopenia at admission is independently associated with physical performance at discharge in older patients with stroke, after adjusting for stroke severity and other clinical variables. Methods: This prospective cohort study included patients with stroke aged 65 years or older admitted to a rehabilitation hospital between November 2021 and August 2024. Sarcopenia was defined by Asian Working Group for Sarcopenia 2019 criteria (handgrip strength and skeletal muscle mass index). Physical performance was assessed using the Short Physical Performance Battery (SPPB) at admission and discharge. Multiple linear regression examined the association between sarcopenia and SPPB scores at discharge, adjusting for age, sex, body mass index, stroke type, premorbid modified Rankin Scale, Charlson Comorbidity Index, Brunnstrom recovery stage, National Institutes of Health Stroke Scale, and SPPB score at admission. Results: Of 198 patients screened, 145 were included in the final analysis (mean age, 76.9 ± 7.1 years; 74 were male), and 85 participants (58.6%) presented with sarcopenia. After adjustment, sarcopenia at admission was independently associated with lower SPPB scores at discharge (β = -0.123; 95% confidence interval: -1.874 to -0.066; P = 0.036). Age, premorbid modified Rankin Scale score, stroke severity, and admission SPPB score were also significant predictors of physical performance at discharge. Conclusions: Sarcopenia is independently associated with poorer physical performance at discharge among older patients with stroke, even after accounting for stroke-related factors. Early identification and management of sarcopenia may allow optimization of rehabilitation outcomes in this demographic, although the clinical significance of this association warrants further investigation.
