Longitudinal Analyses of Early Verb Production in Autism Spectrum Disorder.
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 1 paper.
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
purposeVerb production in childhood predicts language outcomes in adulthood for individuals on the autism spectrum, but few studies have investigated early verb production in ASD, and methodological differences have led to conflicting results. Thus, the purpose of this study was to explore development of verb production in children with autism spectrum disorder (ASD) and typically developing (TD) children.
methodsWe analyzed verb production via language samples from 67 children (N
resultsWe found that verb production increased over time in both the ASD and TD groups, but the TD group increased at a faster rate. However, latent class analysis of verb trajectories yielded three profiles of verb development, the lowest of which consisted entirely of children with ASD and was driving the group difference. We also found that longitudinal analysis can contribute to our understanding of verb development: our latent class analysis of trajectories revealed more nuance than a single-datapoint clustering method, and early verb vocabulary growth predicted later language outcomes for children with ASD.
conclusionOur results suggest that while some children with ASD experience persistent challenges in verb vocabulary growth, others demonstrate similar verb growth to their TD peers. Future work will investigate early factors that differentiate children whose verb production progresses from children whose verb production stays constant over time.
