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
Walking instability increases the risk of falls and compromises mobility safety. This study aimed to explore the impact of various percentages of preferred walking speed (PWS)-specifically, 40%, 55%, 70%, 85%, 100%, 115%, 130%, and 145%-along with age-related changes, on walking stability during treadmill walking. Kinematic marker data from all walking speed trials were pooled for analysis, involving a total of 26 participants (13 young adults aged 24.7 ± 2.4 years and 13 older adults aged 60.8 ± 6.4 years). These pooled data were then decomposed into various movement components (i.e., movement strategies), known as principal movements (PMs), using principal component analysis (PCA). These PMs, which resemble the phases of a gait cycle, collectively contribute to the accomplishment of the walking task. The participant-specific largest Lyapunov exponent (LyE) was employed to assess the local dynamic stability of individual PMs, with lower LyE values indicating higher stability, thereby allowing for the examination of walking speed and age effects. The main findings revealed that only the effects of altered walking speeds were observed; specifically, the LyE value for the midstance phase (PM
