Blue Light Defocus Induces A Positive Effect on Refractive Status and Ocular Health: A Randomized Crossover Trial.
Article in Global challenges (Hoboken, NJ), 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
This randomized crossover trial investigates the effects of blue light defocus display technology on refractive status, axial length (AL), retinal blood flow, and visual function in adults. Twenty-one participants completed all four interventions: 0D, 1D, 2D defocus, and 1D defocus with 30 % blue light filtering (1D+BLF) in a randomized order during standardized visual tasks. Pre- and post-task assessments include refraction, AL, choroidal thickness (ChT), retinal defocus, reading efficiency, and visual fatigue. Results demonstrate that 1D defocus reduces spherical equivalent refraction (SER) (-4.35 ± 2.66 D to -4.21 ± 2.66 D,
