Emotional Prosody Recognition in Autism Spectrum Disorder Without Intellectual Disability: A Systematic Review and Meta-Analysis.
Synthesis in Journal of autism and developmental disorders, 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
Emotional prosody recognition is vital for social interaction and has become a key focus in autism research. However, findings regarding emotional prosody recognition in individuals with autism spectrum disorder without intellectual disability (ASD-without-ID) remain inconsistent. This study aims to address this inconsistency through a systematic review and meta-analysis, exploring potential factors that may account for the inconsistent results. A search across four major electronic databases identified 29 eligible studies comparing emotional prosody recognition in ASD-without-ID and typically developing (TD) participants. We identified several participant- and methodology-related moderators across these studies. Using a random-effects model, we found a moderate-to-large pooled effect (Hedges' g = - 0.65) for emotional prosody recognition in ASD-without-ID participants, which remained stable after adjusting for publication bias through the trim-and-fill method. Emotional complexity and participant age significantly moderated the heterogeneity of effect sizes across studies. The results indicate moderate differences in the recognition of basic emotions through prosody between individuals with ASD-without-ID and TD individuals, with more pronounced differences for complex emotions. The findings emphasize the distinct developmental trajectories of ASD-without-ID individuals. We highlight the need for further investigation into the underlying factors and mechanisms affecting emotional prosody recognition in this population, including meta-analyses examining the moderate effects of various IQ measures and studies involving speakers of tonal languages.
