Impact of tablet's correlated color temperature on ocular and visual function in myopic children: a pilot study.
Article in Frontiers in medicine, 2026. 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: This study aimed to determine whether a tablet's correlated color temperature (CCT) setting affects ocular and visual function in myopic children. Methods: A total of 24 myopic children participated in this study. They were asked to watch a 30-min video at a distance of 33 cm on tablets with low (2800 K) and high CCT (8500 K) settings, in a random order on two different days. Near work-induced transient myopia (NITM), binocular vision function, tear break-up time (TBUT), and asthenopia questionnaire responses were evaluated before and immediately after the 30-min video-watching task. Results: A significant interaction (CCT setting*examination time) ( Conclusion: The 30-min tablet usage task decreased tear film stability and exacerbated some asthenopia symptoms but did not significantly affect other visual functions, regardless of the screen's CCT setting. The use of a high-CCT (8500 K) tablet induced a slightly, but significantly, higher initial NITM compared to a low-CCT (2800 K) tablet; however, given the small magnitude of this difference, its clinical relevance still needs to be confirmed.
