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

purposeThe purpose of this longitudinal investigation was to compare the developmental trajectories of code-related emergent literacy skills of children who are deaf and hard of hearing (DHH) who use amplification and spoken language across the preschool years.

methodThirty children who are DHH and 31 children with typical hearing completed a language and emergent literacy assessment at 6-month intervals from age 4 through 6 years. Growth curve analysis was used to compare developmental trajectories between groups of the code-related skills of phonological awareness, phonological memory, phonological recoding, alphabet knowledge, and conceptual print knowledge.

resultsGrowth across the preschool years was observed on all code-related emergent literacy skills across groups. Children who are DHH scored consistently lower than children with typical hearing on phonological awareness, phonological memory, and conceptual print knowledge; no group differences were observed for phonological recoding or alphabet knowledge. No interactions of time and group were significant.

conclusionsChildren who are DHH exhibit consistent deficits in phonological awareness, phonological memory, and conceptual print knowledge across the preschool years and begin formal literacy instruction with a weaker foundation in emergent literacy skills. Future work should focus on optimizing emergent literacy interventions for children who are DHH during the preschool years. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.21998153.
