Neural contrast sensitivity is not affected by myopic blur.
Article in Scientific reports, 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
The prevalence of myopia is increasing worldwide, accompanied by an increase of potentially under-corrected myopes. Because neural pathways are prone to adaptation in relation to the sensory input, we wondered to what extent neural contrast sensitivity (NCS) is altered in the presence of image blur arising from under-correction. No significant differences in NCS were observed between the three groups but were significantly equivalent between emmetropes, well-corrected, and under-corrected myopes (all p < 0.001). Across all healthy participants, NCS variability increased with increasing spatial frequency which could not be explained by variations in foveolar cone density. For an albinism patient, a large difference between the cut-off frequency and central cone density derived Nyquist sampling limit was observed. In conclusion, NCS is unaffected by myopia and remains stable for under-correction of up to 1.5 D. Furthermore, NCS testing can relate visual deficits to an underlying neurological disorder.
