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: In this study, we aimed to analyze the differences in ankle quasi-stiffness between the dominant and non-dominant sides during obstacle negotiations in older adults and examine their relationship with postural stability. Methods: A total of 16 older adult participants performed 10 obstacle-crossing trials with each limb. The margin of stability (MoS), ankle quasi-stiffness, and integrated electromyography of the tibialis anterior, soleus, and gastrocnemius lateralis in the stance limb were analyzed. Results: Negative correlation was found between frontal-plane stiffness ( Conclusion: During obstacle negotiation, when using the dominant side, ankle quasi-stiffness was lower to enhance postural stability, whereas when using the non-dominant side, ankle quasi-stiffness was greater for faster obstacle negotiation. These findings highlight distinct limb-dominance-based strategies when dealing with complex dynamic tasks. Future training methods and assistive device designs should be specifically targeted to the distinct functional roles of each limb.
