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

Background: Non-strabismic binocular dysfunction can cause visual discomforts such as intermittent diplopia, blurriness, and asthenopia. This study investigates the impact of binocular dysfunction on cybersickness and postural control during Virtual Reality (VR) viewing, providing valuable insights for VR technology development. Methods: A sample of 46 young adults (mean age 22.3 ± 1.98 years; 22 males and 24 females) was divided into a binocular dysfunction group (23 individuals) and a normal group (23 individuals) for comparative analysis. The binocular dysfunction group consisted entirely of individuals with exophoria, indicating a convergence-related fusional deficit rather than an accommodative problem. Participants underwent visual function assessments and completed the Ocular Visual Discomfort and Quality of Life (COVD-QOL) survey, and the Virtual Reality Sickness Questionnaire (VRSQ). Postural control was evaluated using the BtrackS balance plate. Results: Results showed that the binocular dysfunction group exhibited significantly greater near exophoria, lower accommodative amplitudes, and reduced positive fusional vergence at both distance and near (
