Objective Evaluation of Relationship Between Tear Film Stability and Visual Fatigue.
Article in Clinical optometry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 investigate the relationship between tear film stability and visual fatigue using two objective measurements: the non-invasive tear film break-up time (NI-BUT) and the binocular fusion maintenance (BFM) test. Methods: Eleven young adult volunteers (age [mean ± standard deviation], 20.7 ± 1.4 years) participated in this study. The NI-BUT was determined using the distortion of the mire ring. BFM was assessed by measuring the transmittance of liquid crystals placed in front of the subject's non-dominant eye when binocular fusion was broken, and non-dominant eye was shifted to heterophoric. The volunteers were administered the NI-BUT and BFM before and after a 30-minute visual task. Results: NI-BUT (pre vs post: 9.12 ± 1.00 s vs 5.69 ± 3.11 s) was significantly shorter in the post-visual task than in the pre-visual task ( Conclusion: These objective findings support the association between tear film stability and visual fatigue.
