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
backgroundThe vestibular system is critical for sensorimotor function, balance control, and gaze stability. Recent research highlights its role in cognitive functions, including attention, memory, and visuospatial skills. The integration of this system is lateralized in the brain. These disorders represent a substantial burden on healthcare systems, and a negative impact on quality of life.
objectivesPrevious research has shown that increased cognitive load can alter vestibular evoked myogenic potentials (VEMPs), suggesting that vestibular function is influenced by cognitive demands. Therefore, this study aims to (1) examine the relationship between cognitive performance, as measured by the Montreal Cognitive Assessment (MoCA), and baseline vestibular function through cervical and ocular VEMPs (cVEMPs and oVEMPs), to determine whether vestibular dysfunction is associated with cognitive decline; (2) assess the association between depression, anxiety, and stress measured by the Depression, Anxiety, and Stress Scale (DASS-21) subscales, and VEMP parameters; and (3) explore the overall interaction between cognitive and affective domains in chronic vestibular dysfunction, providing insight into the neurophysiological links between balance, cognition, and emotion. METHODOLOGY: Patient data was retrieved from the Otoneurology Service database at the National Institute of Rehabilitation Luis Guillermo Ibarra Ibarra, covering the period from January 2017 to December 2019. This study was conducted from 2022 to 2025. Data included: self-reported scores from the DASS-21 and results from the MoCA test. For data analysis, descriptive statistics, bivariate frequency tables, and the Shapiro-Wilks test, were used to characterize the variables. Spearman's correlation coefficients were then used to evaluate the relationship between MoCA scores, the scores from the DASS-21 scales (depression, anxiety, and stress), cVEMP, and oVEMP values, using a
resultsIn this study of 29 subjects, a demographic analysis revealed a slight female predominance, with 18 subjects (62.1%) female and 11 subjects (37.9%) male. The mean age was 49 years. The most prevalent diagnosis was right vestibular dysfunction, which affected 17 subjects (58.6%), with dizziness being the most common accompanying symptom, also reported by 17 subjects (58.6%). A subsequent Spearman correlation analysis revealed a positive and statistically significant (
conclusionsA positive and statistically significant medium correlation was found, using both Spearman's correlation coefficient and linear regression, between cognitive function and amplitude of vestibular response in the right oVEMP. Conversely, this study found no significant correlation between vestibular evoked myogenic potentials, cervical or ocular, and the variables for the DASS-21. Though further research needs to be done to definitively determine the relationship between the vestibular system, cognition, and cognitive states, this study provides valuable preliminary insights.
