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

This longitudinal study compares concept vocabulary knowledge of children with cochlear implants (n = 40) and children with hearing aids (n = 30) to that of their typical hearing peers (n = 40). Participants completed the Bracken Basic Concept Scale: Expressive (BBCS:E) at ages 4 and 6. Results revealed significant differences in concept vocabulary knowledge between both groups of children who are deaf or hard of hearing (DHH) and the typical hearing group. Although all groups improved BBCS:E test performance between ages 4 and 6, the rate of improvement in children who are DHH did not trend toward catching up over time. Omnibus expressive vocabulary outcomes predicted BBCS:E performance, but age of amplification did not. These preliminary data suggest persistence in concept vocabulary deficits in children who are DHH and developing spoken language, at least through entry into elementary school.
