Local and Global Visual Processing in Autism: A Systematic Review and Meta-Analysis of Neuroimaging Studies.
Article in Journal of autism and developmental disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeAutism Spectrum Condition (ASC) is linked to altered local and global visual processing. Previous meta-analyses demonstrated brain activation differences across a broad range of visual tasks in ASC compared to non-autistic individuals, suggesting alterations in visual processing. However, a more specific understanding of brain mechanisms underlying detail-oriented visual attention is still lacking. To address this question, we conducted a systematic review and an activation likelihood estimation (ALE) meta-analysis on brain imaging studies assessing 252 individuals with ASC and 263 neurotypical controls (CON).
methodsWe included tasks that either required focusing on details while ignoring global configurations (local visual processing) or vice versa (global visual processing). Using ALE, we performed between-group and within-group meta-analyses across 15 studies involving local and global visual tasks.
resultsWe found greater activation in the right inferior occipital gyrus (Brodmann Area, BA 19) in ASC compared to CON in the between-group meta-analysis of local and global visual studies. In the within-group analysis, we identified two activation convergences in the thalamus and middle occipital gyrus (BA 19) in the ASC group, and one in the inferior parietal lobule (BA 40) in the CON group.
conclusionsIn line with theories suggesting alterations in local and global visual processing in ASC, our results indicate that autistic individuals may rely more on the visual cortex for local/global visual processing, while non-autistic controls may rely more on parietal regions.
