A Preliminary Study on Comparative Eye Tracking Analysis Using a Meta Quest Pro.

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
The eye and facial tracking technology incorporated in the Meta Quest Pro plays a significant role in research exploring visual attention, cognitive processes, user interaction, and human behavior analysis. However, differences in eye anatomy, such as Outer canthal distance (OCD), Interpupillary distance (IPD), and Intercanthal distance (ICD), may impact the accuracy & reliability of eye movement data. This preliminary study aims to evaluate the impact of inter-eye distance variations on eye-movement-based feature extraction in VR environments using the head-mounted device Meta Quest Pro. The data collection process involved the recruitment of 16 participants, comprising 10 males and 6 females, within the age range of 21 to 30 years. This specific range was selected to minimize inter-individual variability, enhance experimental control, and ensure consistency in cognitive and behavioral responses, given that reaction time, attentional regulation, and visual processing speed are known to vary with age. The process is followed by eye measurements (OCD, IPD, and ICD), an eye calibration test before the experiment, and 3 experimental tasks: fixed gaze task, regular eye movement task, and irregular eye movement task. The Meta Quest Pro recorded participants' eye movements while they performed VR-based tasks, followed by the extraction of eye-related features from the device. The dataset underwent Shapiro-Wilk, and D'Agostino-Pearson normality tests, followed by statistical analysis (Spearman Correlation, Kruskal-Wallis, and Mann-Whitney
