Sociodemographic and Health-Related Disparities in 24-Hr Movement Cycles Among Older Adult Women: The Study of Women's Health Across the Nation.
Article in Journal of aging and physical activity, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundThe 24-hr movement cycle is associated with health, but less is known about factors associated with differences in cycle composition.
methodsData from 1,297 Study of Women's Health Across the Nation participants (ages 60-72 years; Mage = 65.4 ± 2.6 years) who concurrently wore hip (waking) and wrist (sleep) accelerometers at Visit 15 (2015-2017) to quantify differences in sleep, sedentary, and physical activity across sociodemographic and health factors are used, including age, race and ethnicity, educational attainment, body mass index, financial strain, self-rated health, body pain, vasomotor symptoms, depression symptoms, anxiety, obstructive sleep apnea, and multimorbidity. We used compositional data analysis to characterize movement cycles and multivariate analysis of variance to examine the difference in the proportion of the day spent in cycle components by subgroup, controlling for Study of Women's Health Across the Nation site, age, race and ethnicity, and body mass index.
resultsOn average, women spent 34.6% (8.3 hr) in sleep and 31.4% (7.5 hr), 30.5% (7.3 hr), and 3.5% (50 min) in sedentary, light-intensity, or moderate- or vigorous-intensity physical activities (MVPA), respectively. Black and Hispanic women; smokers; and those who reported moderate/severe financial strain, moderate/severe bodily pain, poor health, or living with multimorbidity spent 19%-34% less time in MVPA relative to the overall mean composition. Women with depression and anxiety symptoms spent 10%-19% less time in MVPA relative to the mean composition.
conclusionVariations in compositions were driven by differences in the proportion of time spent in MVPA. Significance/Implications: Identifying persons with inadequate movement profiles could help inform targeted strategies for intervention and policies.
