Alterations in tear film and wavefront parameters associated with different types of disposable surgical masks in healthcare personnel during working hours: a randomized trial.
Article in Therapeutic advances in ophthalmology. 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
Background: Facial masks are essential for preventing respiratory infections, particularly among healthcare workers. However, prolonged mask use may lead to ocular surface disruption, known as mask-associated dry eye (MADE). Objectives: To evaluate the impact of different types of disposable surgical masks on tear film parameters and corneal wavefront aberrations during an 8-h work shift. Design: Randomized clinical trial. Methods: Sixty healthcare personnel at Rajavithi Hospital were randomly assigned to three mask groups: Group 1 (earloop surgical mask; Medimask Results: TMH decreased significantly in all groups: Group 1 from 201.13 ± 85.10 µm to 174.53 ± 42.01 µm ( Conclusion: An 8-h shift of mask use reduced TMH across all groups and increased conjunctival redness in earloop surgical masks without adhesive. Although most optical aberrations remained unchanged, elevated HOAs in the anti-fog earloop surgical mask group may affect vision quality under mesopic conditions.
