Possible Sarcopenia is Related to Leisure-Time Physical Activity but Not to Occupational Activity.
Article in Annals of geriatric medicine and research, 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
backgroundPhysical activity (PA) has long been considered a key strategy in the management of sarcopenia. To our knowledge, this is the first study to examine domain-specific physical activity, including leisure-time and occupational activities, in relation to possible sarcopenia (PS) among middle-aged and older adults.
methodsWe analyzed a total of 15,819 adults aged ≥40 years. PS was defined on the basis of handgrip strength (males <28 kg and females <18 kg) according to the Asian Working Group for Sarcopenia. The Global Physical Activity Questionnaire was used to evaluate domain-specific PA, including weekly leisure-time or occupational moderate-to-vigorous PA (MVPA). MVPA was classified into three categories: no activity, 1-149 min/week, and ≥150 min/week. Parameters potentially related to PS or PA were included as covariates: age, sex, household income, education, medication, alcohol and smoking habits, nutritional status, and body weight.
resultsCompared with participants with no leisure-time MVPA, those with 1-149 min/week and ≥150 min/week of leisure-time MVPA had odds ratios (95% confidence intervals) of 0.64 (0.54, 0.74) and 0.60 (0.52, 0.68) for PS, respectively (p<0.001 for both). However, occupational MVPA was not significantly related to PS. Subgroup analyses stratified by sex, age, and sedentary time revealed no significant heterogeneity (all p-values for interactions >0.05).
conclusionThese findings demonstrate that PS is inversely related to leisure-time PA but not to occupational PA among middle-aged and older adults, suggesting that PA programs that focus specifically on leisure-time activities may be necessary to prevent and manage possible sarcopenia.
