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
introductionShoe insoles that provide a single source of plantar sensory stimulus, such as texture or vibration, can improve measures of standing balance. Vibrotexture insoles, designed to provide multiple sources of sensory stimuli, may provide greater benefits. This study aimed to investigate the immediate effects of wearing Vibrotexture insoles on quiet standing balance and lower limb muscle activity in healthy young adults.
methodsThirty healthy young adults (16 males, 23.6 ± 3.9 years) performed standing balance tests (eyes open/closed, firm/foam surface) wearing four different insoles (vibrotexture, textured, vibrating, and control) within standardized shoes. Balance outcomes included center of pressure (COP) velocity, COP anteroposterior and mediolateral (ML) path length and range. Lower limb muscle amplitude was examined using electromyography at the medial gastrocnemius, soleus, peroneus longus, rectus femoris, biceps femoris, and gluteus medius (dominant leg). Perceived insole comfort and user experience was reported. One-way Friedman tests were used to compare differences between insoles.
resultsFor the primary aim of interest, there were no differences in balance measures or muscle activity between the vibrotexture insoles and other insole conditions. Exploratory secondary analyses revealed that COP ML path length was less while wearing the textured compared to vibrating insoles (eyes open, firm surface) (p = 0.022), and rectus femoris muscle amplitude was less while wearing the textured compared to control insoles (eyes open, foam surface) (p = 0.027). The vibrotexture insoles were perceived as less comfortable than the control insoles (p < 0.013). Participants commonly reported the sensory-stimulating insoles to feel "spiky", "tingly", or "rough".
conclusionWearing vibrotexture insoles for the first time does not appear to alter standing balance in young adults. However, textured insoles do alter COP ML path length and rectus femoris amplitude. These findings highlight the need to investigate vibrotexture insoles in more dynamic tasks and in populations with reduced foot sensation, where their effects may be more pronounced.
