Does sit-to-stand transition velocity vary across the day? Association with physical functioning and fatigability in community-dwelling older adults.
Article in Innovation in aging, 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 and Objectives: Physical fatigability increases with age and may act as a barrier to activity and a marker of functional decline. In older adults, strength-demanding, device-based variables such as free-living sit-to-stand (STS) transitions may be associated with physical fatigability. This study examines STS velocity patterns across a 24-hr cycle and their associations with physical fatigability and functioning in older adults. Research Design and Methods: This cross-sectional study included a population-based sample of 75-, 80-, and 85-year-old people ( Results: Individuals with high self-reported walking fatigability showed greater declines in free-living STS angular velocities in the late afternoon (4-6 p.m.: odds ratio [OR] = 1.39 per 5% decrease, Discussion and Implications: Measuring STS velocity decline may help in the identification of older individuals with higher fatigability and poorer physical functioning and may open new possibilities for wearable-based remote monitoring and individualized care.
