Speech Perception Development From Childhood to Adulthood Following Pediatric Cochlear Implantation: A 30-year Longitudinal Study.

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
Objective: Speech perception development in pediatric cochlear implant users varies widely, and its progression into late childhood and early adulthood remains unclear. This study examines long-term developmental trajectories and influencing factors using a longitudinal clinical dataset. Study design: Speech perception data collected across 22 clinical tests conducted in English and in quiet were retrospectively analyzed with a hierarchical scoring system to understand development of 294 pediatric cochlear implant users between 1992 and 2024 at Boys Town National Research Hospital. Medical records provided data on age at cochlear implant activation, year of first cochlear implant implantation, device configuration, daily device use, hearing loss etiology, revision history, primary language use, insurance type, race, and comorbidities. These variables were incorporated into statistical models to predict longitudinal speech perception outcomes. Results: Pediatric cochlear implant users generally show steady improvement in speech perception with chronological age. Faster early development of speech perception was associated with implantation before 18 months of age, bilateral cochlear implant use, longer daily device use, spoken English as a primary language, having private insurance, and better vestibular function. Alternatively, auditory neuropathy, syndromic hearing loss, hearing loss due to prenatal infections and low socioeconomic status were associated with poorer speech perception. Conclusions: Auditory neuropathy or syndromic hearing loss and low socioeconomic status are key factors associated with slower speech perception development. Improving access to cochlear implant specialists and encouraging consistent device use-especially for later implantees-may enhance outcomes. Additional support for families and educators is recommended to promote increased device use.
