1 · What the graph read from it

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.

2 · The registry

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

purposeAge-related physiological changes affect neuromuscular control, potentially increasing functional limitations and fall risk among older adults. The aim of this study was to investigate how age affects various aspects related to pivoting neuromuscular control during stepping tasks, such as stepping speed, pivoting instability, and entropy of time to peak electromyography (EMG) in lower extremity muscles.

methodsTwenty-three healthy individuals (12 young and 11 older) participated in this study. Participants performed stepping tasks on a modified stepper that allowed pivoting motion, defined as rotational movement in the transverse plane at the knee joint (i.e., tibial rotation relative to the femur). When performing stepping tasks while controlling a pivoting motion, stepping speeds, pivoting instability, and entropy of time to peak EMG of lower extremity muscles were assessed and compared between young and older groups.

resultsThe older group showed significantly lower stepping speed (p < 0.05), greater pivoting instability (p < 0.05), and higher entropy of time to peak EMG (p < 0.05), compared to the young group.

conclusionOlder adults exhibited lower ability in pivoting neuromuscular control compared with the young individuals during the stepping task. These findings may enhance our understanding of the potential risk factors for injury associated with age-related differences in pivoting neuromuscular control.
