Speed of Voluntary Step Execution May Predict Survival among Older Adults: An Explorative Study.

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
<p>Introduction: With the growing population of older adults, predicting survival through clinical examinations has gained an increased interest. We aimed to evaluate the relationship between balance measures, such as postural sway and voluntary stepping performance and survival.
methodsThis study analyzed balance parameters, collected from previous studies conducted between 2005 and 2011, including postural sway, stabilogram diffusion analysis (SDA) in standing, and voluntary step execution. Cox proportional hazards regression analyses were performed to examine associations between balance parameters and mortality.
resultsVoluntary stepping performance, especially under dual-task (DT) condition, was associated with survival. Slower step initiation time was associated with higher mortality risk; with every 0.100 s increase, the survival hazard rate ratios decreased by 28%. Postural sway parameters, particularly increase in anterior-posterior sway velocity, demonstrated predictive ability but less effective than voluntary stepping test parameters. Among SDA measures, higher critical displacement tended to show an association with lower survival in older adults.
conclusionThese findings align with prior research regarding physical performance indicators, such as gait speed, to survival. Voluntary stepping under DT conditions extends this understanding by capturing both physical and cognitive functions, offering a more integrated survival assessment. Voluntary stepping performance, in DT conditions, may be a valuable predictor of survival in older adults. Incorporating DT-based assessments into clinical evaluations could improve survival prediction and guide early interventions targeting cognitive-motor health. Future studies should explore the longitudinal impact of voluntary stepping on survival, assessing whether cognitive-motor training for balance rehabilitation can enhance survival rates. </p>.
