Baseline Function Predicts Gains in Both Speech Recognition and Quality of Life After Cochlear Implantation.
Article in Otology & neurotology : official publication of the American Otological Society, American Neurotology Society [and] European Academy of Otology and Neurotology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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 characterize patterns of improvement in speech recognition and quality of life (QOL) after cochlear implantation and examine how baseline performance, device use, and candidacy status ("borderline," qualifying in noise only vs. "traditional," qualifying in quiet) predict postoperative gains in both domains. STUDY
designRetrospective cohort study.
settingTertiary referral center. PATIENTS: One hundred one adult unilateral CI recipients implanted between 2019 and 2023 with complete preoperative and postoperative (6 or 12 mo) speech recognition and QOL data.
interventionsUnilateral cochlear implantation.
main outcome measuresAzBio sentence recognition in quiet (AzBioQ) and Cochlear Implant Quality of Life (CIQOL) Global scores. Clinically meaningful improvement was defined using validated thresholds for each measure.
resultsOf 101 patients, 97 demonstrated clinically meaningful improvement in at least one domain: 44 improved in both speech recognition and QOL (dual improvers), 43 in speech recognition only, 10 in QOL-only, and 4 showed no significant improvements. Patients with lower baseline scores in a given domain demonstrated greater gains in that domain. Greater daily device use ("datalogging") was associated with larger speech-recognition gains ( r =0.34, P <0.01) but not QOL improvements ( r =0.12, P =0.24). Borderline candidates (n=24) achieved QOL gains comparable to traditional candidates (n=77) despite smaller speech-recognition improvements.
conclusionsThe vast majority of CI recipients demonstrate meaningful improvements in speech recognition, QOL, or both domains. Baseline performance predicts domain-specific gains, and borderline candidates achieve meaningful QOL benefits despite smaller speech-recognition gains. These findings provide further support for incorporating patient-reported outcome measures into candidacy evaluations and postoperative assessments.
