Visual Neural Dynamics of Adolescents with Myopia During Face Inversion: An ERP and Oscillatory Study.
Article in Brain sciences, 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
backgroundThis study aimed to investigate how myopia affects early event-related potential (ERP) components and neural oscillatory activity during a face inversion task in adolescents, in order to clarify the potential mechanisms by which degraded visual input influences facial structural encoding and neural dynamic regulation.
methodsForty-eight adolescents aged 13-17 years participated, including 24 with myopia and 24 with normal vision. EEG signals were recorded while participants performed a classic upright-inverted face recognition task. A mixed-design ANOVA was applied to compare group differences in the amplitude and latency of the P1 and N1 components. Time-frequency analyses were conducted to assess task-related oscillatory power in the θ (4-7 Hz) and α (8-13 Hz) bands.
resultsNo significant group differences were found in P1 amplitude or latency, whereas the N1 latency was significantly longer in the myopia group (
conclusionsMyopia in adolescents is associated with delayed neural processing during facial structural encoding and enhanced θ-α oscillatory activity within early post-stimulus periods, which may reflect altered early neural engagement in response to degraded visual input. These findings indicate that the effects of myopia extend beyond optical defocus to involve perceptual-cognitive integration, providing novel evidence for the neurodevelopmental characteristics and regulatory mechanisms of adolescent myopia.
