Association Between Preoperative Negative Emotional States and Eye Movement During Photorefractive Keratectomy.
Article in Journal of ophthalmic & vision research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Purpose: To describe the link between negative emotions-depression, anxiety, and stress-and eye movement during photorefractive keratectomy (PRK). Methods: This comparative case series was conducted on 53 PRK candidates and involved completing the Depression, Anxiety, and Stress Scale (DASS-21) before surgery. Eye movement, measured as the radial distance between the pupil and laser center during each shot, was analyzed. Average distance indicated centralization accuracy, while standard deviation (SD) indicated precision. Stress, depression, anxiety, and their relationship with eye movement during PRK were studied. Results: The mean and SD of eye movements were not significantly correlated with depression, anxiety, stress, or the total DASS-21 score. A weak negative correlation was observed between the preoperative spherical equivalent (SE) and stress ( Conclusion: The DASS-21 questionnaire showed no link between negative emotions and eye movement. Additionally, longer ablation times correlated with greater SD of eye movement.
