Associations between walk ratio and osteoporosis and sarcopenia in community-dwelling older women.
Article in Physical activity and nutrition, 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
purposeThe objective of this study was to analyze the associations between walk ratio and the prevalence of osteoporosis and sarcopenia among older women in the community.
methodsA total of 225 community-dwelling older women participated in the study. All participants underwent standardized assessments of body composition, anthropometry, and gait parameters. Based on walk ratio, which was calculated based on step length and cadence, participants were categorized into the lowest tertile, middle tertile, and highest tertile, corresponding to the lowest, middle, and highest 33%, respectively. Osteoporosis and sarcopenia were classified based on femoral neck bone mineral density and the appendicular skeletal muscle mass index, respectively. Binary logistic regression was used to estimate the odds ratios (ORs) for exposure to osteoporosis and sarcopenia across walk ratio levels.
resultsAfter adjusting for covariates, results showed that individuals in the lowest tertile had significantly higher odds of having osteoporosis (OR = 2.240, 95% CI = 1.031-4.866, p = .004) and sarcopenia (OR = 2.848, 95% CI = 1.271-6.383, p = .011) than those in the highest tertile (OR = 1, reference). Additionally, the odds of concurrent exposure to osteosarcopenia were significantly higher in the lowest tertile (OR = 5.902, 95% CI = 1.209-28.819, p = .028) compared to the highest tertile (OR = 1, reference).
conclusionThese findings suggest that a low walk ratio is an independent risk factor for both osteoporosis and sarcopenia, and may serve as a predictive indicator capable of simultaneously identifying osteosarcopenia.
