Effects of age, sex, and sensory information on balance performance in young and older adults.

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: This study aimed to comprehensively investigate the independent and interactive effects of age, sex, and sensory information on balance control in young and older adults. Methods: A total of 250 participants, stratified into five age groups (25-40, 60-65, 66-70, 71-75, and 76-80 years) with equal sex distribution, underwent the Sensory Organization Test (SOT) using computerized dynamic posturography. Balance was assessed using center of pressure (COP) velocity and displacement across six sensory conditions that selectively challenged and altered the availability and reliability of visual, proprioceptive, and vestibular information, thereby eliciting adaptive multisensory reweighting rather than isolating individual sensory systems. A 5 (age group) × 2 (sex) × 6 (sensory condition) repeated-measures ANOVA was used for analysis. Results: The analysis revealed significant main effects of age group and sensory condition on both COP velocity and displacement (age group: p < 0.001 for all; sensory condition: p < 0.001 for all), with balance performance systematically declining with each successive age group and as sensory conditions became more challenging. No significant main sex effects were found. Critically, significant interactions revealed that the detrimental effects of age and sensory conditions were not uniform across all groups. Notably, the effect of challenging sensory conditions was more pronounced in older adults (age × condition, p < 0.001, Conclusion: Balance control is profoundly influenced by age and the availability of accurate sensory information, with older adults, especially the oldest old, demonstrating significantly greater impairment under sensory-challenging conditions. While sex alone was not a dominant factor, its interaction with age suggests that the oldest females may represent a particularly vulnerable subgroup.
