Association of stroke with possible sarcopenic obesity and the modified effect from healthy lifestyle: a cross-sectional study based on CHARLS.
Article in BMC public health, 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
backgroundSarcopenic obesity (SO), a metabolic disorder, may establish a bidirectional vicious cycle with stroke. However, the relationship between SO and stroke remains unclear. This study aims to analyze the association between these two diseases and to investigate the moderating effect of healthy lifestyle.
methodsThis cross-sectional study used data from the 2015 China Health and Retirement Longitudinal Study database. Participants meeting the inclusion criteria were classified based on the 2019 Asian Working Group for Sarcopenia (AWGS) criteria, and their history of stroke was recorded through questionnaires. The lifestyle assessments were based on four dimensions: smoking status, alcohol consumption, social engagement, and sleep duration. Logistic regression models examined the association between possible SO and stroke and the moderating role of a healthy lifestyle. Finally, a sensitivity analysis was performed.
resultsA total of 5,401 individuals were included in the study, 185 of whom were diagnosed with possible SO. Compared to the non-SO group, the SO group had significantly higher rates of diabetes mellitus, cardiac disease, stroke, fall history, and drug use. Logistic regression analysis revealed a significant association between possible SO and stroke (OR = 2.42, 95%CI: 1.43–4.11, P = 0.001). The association was weaker in the high score healthy lifestyle subgroup (OR = 2.38, 95%CI: 1.21–4.70, P = 0.01) than in the low score subgroup (OR = 2.43, 95%CI: 1.02–5.80, P = 0.045). Sensitivity analyses confirmed the stability of the results.
conclusionThis study provides evidence that possible SO is significantly associated with stroke. Adhering to a healthy lifestyle, including abstaining from smoking and alcohol consumption, engaging in social activities, and maintaining adequate sleep, might attenuate this association. CLINICAL
