Prosodic Imitation in Children With Down Syndrome: Evidence From Sentence Repetition and Pitch Contour Modeling.
Article in American journal of speech-language pathology, 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
purposeThis study examined prosodic speech production in children with Down syndrome (DS) using a structured imitation task designed to elicit sentence-level fundamental frequency (
methodFourteen children with DS and 22 typically developing (TD) children completed a sentence repetition task with four prosodic conditions: neutral statements, yes/no questions, subject emphasis, and object emphasis. Productions were acoustically analyzed with generalized additive mixed models to model time-varying
resultsBoth groups modulated
conclusionsChildren with DS are able to produce some prosodic contrasts in imitation, but their pitch trajectories were flatter and showed reduced contrastiveness compared to their TD peers. Whereas the present study focused on
