1 · What the graph read from it

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.

2 · The registry

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

purposeEarly interventions for children at risk for developmental language disorder (DLD) have not systematically targeted the transition from vocabulary to syntax. This randomized controlled trial examined short-term effects of the Enhanced Milieu Teaching-Sentence Focused (EMT-SF) intervention, an 18-month multiphase intervention, on vocabulary after 6 months (child age = 36 months) and grammar after 12 months (child age = 42 months).

methodParticipants included 108 children at risk for DLD between 30 and 31 months of age and their caregivers. Participants spoke only English in the home and were primarily from White, non-Hispanic, college-educated families. Children were randomly assigned to the treatment or control group. Interventionists coached caregivers on EMT-SF strategies via telehealth. Following 6 months of intervention, a latent variable composed of Peabody Picture Vocabulary Test-Fifth Edition (PPVT-5) and Expressive Vocabulary Test-Third Edition scores characterized vocabulary outcomes. Following 12 months of intervention, a latent variable composed of scores on the Structured Photographic Expressive Language Test-Preschool 2 and the Test of Early Grammatical Impairment characterized grammar outcomes.

resultsAt 36 months, mean vocabulary scores for both groups fell within the average range. Structural equation modeling (SEM) revealed no significant short-term treatment effect on the vocabulary latent variable (

conclusionsThe EMT-SF treatment group demonstrated significantly higher single-word receptive vocabulary scores at 36 months and grammar scores at 42 months than the control group. Grammatical difficulties persisted for most children in both groups at 42 months, further documenting that grammar is a particularly vulnerable language domain for children at risk for DLD.
