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

The purpose of this study was to compare developmental trajectories of oral language acquisition of children who are deaf and hard of hearing (DHH) and children with typical hearing across the preschool years. Thirty children who are DHH who use amplification and spoken language and 31 children with typical hearing completed an early language and literacy assessment battery every six months from age 4 to age 6. The developmental trajectories of each group's language skills were examined via growth curve analysis. Oral language skills were lower for children who are DHH than for children with typical hearing at study entry. For vocabulary, children who are DHH demonstrated growth over the two years but did not close the gap in performance over time. For morphosyntax, specifically verb tense marking, children who are DHH demonstrated growth over preschool, becoming more adult-like in their productions.
