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

IntroductionMaintaining balance is a complex process involving the integration of information from the visual, vestibular, and somatosensory (VVS) systems, along with autonomic nervous system (ANS) function. Traditional assessments of these systems are often expensive, limited to specialised settings or focus on overall balance outcomes, potentially overlooking deficits in the individual systems. This study aimed to evaluate the test-retest reliability of a novel, fully portable clinical assessment tool designed to provide objective measures for individual components of the VVS system and ANS function.MethodsTwenty-eight participants (aged 20-88 years), with no comorbidities and meeting Australian physical activity guidelines, completed the protocol twice. The novel clinical assessment tool comprised of two systems: (1) a virtual reality-type headset incorporating eye-tracking to evaluate visual-vestibular function (smooth pursuit and voluntary saccades), and autonomic function (pupil light reflex); and (2) the Active Movement Extent Discrimination Apparatus (AMEDA) for somatosensory function. Reliability was assessed using two-way mixed-effects model (consistency type, single rater) Intraclass Correlation Coefficients (ICC 3,1) calculated in R-studio. The standard error of measurement (SEM) and minimal detectable change (MDC) was also calculated. Bland-Altman plots were utilised to visualise the agreement between two test repeats.ResultsEach metric demonstrated at least moderate to good test re-test reliability: left and right AMEDA (ICC = 0.69 and 0.75), smooth pursuit (ICC = 0.67), voluntary saccades (ICC = 0.53), autonomic response delay (ICC = 0.80), parasympathetic function (ICC = 0.86), and sympathetic function (ICC = 0.89).DiscussionThis study supports the reliability of a new, fully portable clinical assessment tool to assess VVS and ANS function. By demonstrating the reliability of this new streamlined tool for evaluating the VVS and ANS systems, the findings of this study has the potential to enhance clinical practice and research in falls prevention and balance rehabilitation.
