Unseen burden: Prevalence and determinants of possible sarcopenia in Indonesian older adults - a secondary data analysis.
Article in Belitung nursing journal, 2026. 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
Background: Indonesia is experiencing rapid population aging, raising concern about muscle weakness in later life; possible sarcopenia offers early identification through low handgrip strength. Objective: To estimate the prevalence of possible sarcopenia and its determinants among older adults in Indonesia. Methods: This secondary analysis used baseline data from the Indonesian Longitudinal Aging Survey 2023 and included adults aged sixty years or older with valid handgrip measurements. Possible sarcopenia followed the Asian Working Group for Sarcopenia 2019 thresholds using the maximum of two trials per hand. Covariates included sociodemographic, behavioral, functional, and clinical factors. We applied descriptive statistics, bivariate tests, and multivariable logistic regression, with probit average marginal effects. Sampling weights were unavailable in the public-use microdata; we treated enumeration areas as the primary sampling units, with available stratification and no weights; estimates were unweighted, and standard errors were design-based (survey-corrected). Results: Among 1,598 participants, the prevalence of possible sarcopenia was 51.1%. Older age, low physical performance, and urban residence were associated with higher odds. Higher body mass index and better cognition were associated with lower odds. A prespecified sex-by-body mass index interaction suggested attenuation of the protective association of body mass index among women. Conclusion: Possible sarcopenia is common among older Indonesians and is patterned by age, body composition, cognition, functional status, and residential context. Community health services, including community nursing services, can integrate routine handgrip assessment with brief interventions on strength activities, nutrition, and cognitive engagement to identify risk early and inform preventive care.
