Is there a neural common factor for visual illusions?
Article in Journal of vision, 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
It has been reported that the surface area of the human primary visual cortex predicts the susceptibility to several spatial contextual illusions. Yet, contrary to common belief, illusions correlate only weakly at the perceptual level, raising the question of how they can correlate with a neural measure like V1 surface area. In addition, mounting evidence suggests that there is substantial interindividual variability not only in neural function and anatomy but also in the mapping between the two, which further challenges the findings of a neural common factor for illusions. In light of these concerns, our first goal was to re-evaluate the previous imaging results. Seeking to investigate whether these findings generalize, we expanded our study to other illusions. We could not replicate previous findings and did not find any other significant correlations, either at the perceptual level or between illusion susceptibility and visual functional neuroanatomy.
