Characteristics of Speech Sound Development in Preterm-Born Children: A Scoping Review.
Review in International journal of language & communication disorders. 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
backgroundThere is substantial evidence for the detrimental impact of preterm birth on language development compared to children born at term. However, little is known regarding speech sound development of preterm infants. Speech development precedes language development and requires investigation in its own right. A clear picture of the evidence for speech sound development in preterm-born children is important to enable clinical services in early identification and intervention for these children.
aimTo understand the extent and type of evidence relating to typical and atypical speech sound development in children born before 37 weeks gestation (preterm).
methodsA search of 5 MEDLINE, CINAHL, PsycInfo, EMBASE, EMCARE was undertaken in April 2026. Grey literature searching in Campbell collaboration, COSMIN, PROSPERO, FigShare and Open Science Framework, Google (advanced search), and SpeechBite was undertaken. Articles including samples of children reporting speech sound development (typical or atypical) were included in the review. Studies focusing on outcomes for reading and literacy were excluded, as were animal studies and those signed languages. Population demographics, assessment and outcome measures, methods of analysis and findings were extracted from each study. MAIN CONTRIBUTION: 28 studies from 14 different countries were included in the review. Twenty-five of the 28 studies reported differences in speech outcomes of PT children and FT children between the ages of 3 months and 12 years.
conclusionsThis review found differences in how PT and FT children develop sounds for speech from birth through into childhood. Further large-scale, longitudinal research is needed to clarify what typical and atypical speech development look like in PT children. WHAT THIS PAPER ADDS: What is already known on this subject The findings of this scoping review provide evidence of the differences between speech sound development between preterm born children and children born at term in the first 12 years of life. This information could contribute to a more informed approach to care and early intervention. What this study adds to the existing knowledge? Understanding the impact of preterm birth on early speech sound development can help speech and language therapists to build a picture of a child's individual risk profile for speech sound disorder later in childhood. This can lead to earlier intervention for the children who need it most.
