Low relative sit-to-stand power in Colombian older adults: Cut-off points and associations with frailty and functional decline.
Article in The Journal of frailty & aging, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesTo examine the association between relative sit-to-stand (STS) power and age, establish sex-specific cut-off points, and evaluate their associations with adverse outcomes in Colombian older adults.
designCross-sectional, population-based study.
settingHealth, Well-being, and Aging Study (SABE-Colombia, 2014-2015).
participants3051 community-dwelling adults aged ≥60 years (56.6 % women; mean age 68.6 ± 6.4 years). MEASUREMENTS: Relative STS power (W·kg⁻¹) was estimated using a validated equation. Quantile regression examined age-related changes across percentiles (Q10-Q90). Receiver operating characteristic (ROC) curves with the Youden index determined cut-off points. Age-adjusted logistic regression tested associations with frailty, functionality as gait speed and handgrip strength (HGS), and depression.
resultsOptimal cut-offs for low relative STS power were 2.11 W·kg⁻¹ for men and 1.63 W·kg⁻¹ for women. Prevalence of low STS power was 34.3 % in men and 34.8 % in women, increasing with age in both sexes. Quantile regression revealed steeper age-related declines at higher percentiles, particularly among men. Low relative STS power was significantly associated with frailty and low functionality.
conclusionRelative STS power is a simple, clinically feasible biomarker to identify functional impairment in older adults. The sex-specific thresholds reported for Colombian populations reflect demographic differences in muscle physiology and decline. Their integration into geriatric practice may enhance early detection, guide preventive interventions, and ultimately improve health outcomes in aging populations.
