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

objectivesThe aim of this study is to show the long-term effects of cochlear implant as a treatment in both children and adults with acquired single-sided deafness. STUDY

designObservational, descriptive, cross-sectional.

settingTertiary referral center. PATIENTS: 21 children and 20 adults with SSD.

interventionsUnilateral CI.

methodsSpeech detection thresholds and disyllabic words test (65 dB SPL) were performed in the modalities azimuth (S0), signal CI side (SCI), and signal on the normal hearing (SNH). The normal ear was masked with both white noise of +10 dB of the hearing threshold and plugging the same ear, whereas the speech testing was performed using the cochlear implant wireless system.

resultsAll results were obtained up to 48 months after the activation of the sound processor. All study subjects showed improvements in speech test results in all conditions tested. Word recognition in noise in children improved from 42.76% at 6 months after activation of the sound processor to 76.38% at 48 months in the S0 condition, from 50 to 78.10% in the SCI condition, and from 38.48 to 66.48% in the SNH modality. Regarding adults, word recognition in noise went from 45.40% at 6 months of activation of the sound processor to 73.40% at 48 months in the S0 condition, from 52.60 to 76.20% in the SCI condition, and from 43.60 to 64.80% in the SCI condition ( p < 0.001). The average duration of use of the speech processor daily was 11 hours in children and 9.4 hours in adults.

conclusionWhen comparing children's performance with adults', progressive improvement in speech discrimination compared with adults was observed.
