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

objectiveTo assess the safety and efficacy of cochlear implantation in adult patients with single-sided deafness (SSD) through a post-market approval study. STUDY

designProspective, nonrandomized, single-arm multicenter post-market clinical investigation.

settingFive tertiary referral cochlear implant (CI) centers. PATIENTS: Thirty adults older than or equal to 18 years with profound unilateral sensorineural hearing loss (pure-tone average ≥ 80 dB HL and CNC ≤ 5%) and normal/near-normal hearing in the contralateral ear (pure-tone average ≤ 30 dB HL).

interventionsUnilateral cochlear implantation with an FDA-approved CI system.

main outcome measuresChanges in speech recognition in quiet and noise, binaural hearing in noise, spatial hearing, tinnitus reduction, and quality of life.

resultsSignificant improvements in speech perception in quiet and noise were demonstrated from the preoperative to the 12-month postoperative timepoint. Target-to-masker separated hearing tasks showed significant improvements for both head shadow and binaural squelch at the 12-month postoperative timepoint. Significant effects of the CI were also seen for tinnitus reduction, quality of life improvement, fatigue reduction, and self-reported benefits.

conclusionsThis prospective, multicenter post-market approval study reports on the outcomes of CI for SSD in a cohort of adult patients. Significant improvements in speech in quiet and noise at 12 months were demonstrated. In addition, significant benefit was observed for all patient-reported outcome measures including tinnitus reduction, listening fatigue, quality of life, and spatial hearing. Cochlear implantation is an excellent treatment option for SSD patients and has a positive impact on many aspects of patients' lives and well-being.
