Longitudinal Cochlear Implant Use in Pediatric Patients With Unilateral Hearing Loss.
Article in Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery, 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 longitudinal cochlear implant (CI) usage patterns in children with unilateral hearing loss (UHL) and evaluate the impact of age at implantation and duration of deafness on device use. STUDY
designRetrospective cohort study.
settingTwo academic tertiary care centers.
methodsPediatric CI recipients with UHL implanted between 2018 and 2024 were included. Datalogging information was obtained at 3, 6, 12, 18, and 24 months postactivation. Patients were categorized as regular users (>6 h/day) or moderate users (>4 h/day). Usage patterns were analyzed using regression.
resultsFifty-three patients with datalogging available at 3 months postactivation (mean age at implantation: 7.3 years; SD 3.6) were included. At 3 months, 81% were regular users and 83% were moderate users, with mean usage of 8.2 h/day (SD 3.4). Usage remained stable over time: at 24 months, among 27 patients with available data, 64% were regular users and 82% were moderate users, with mean usage of 6.8 h/day (SD 2.9). Among regular users with sustained use at 6 months, mean usage decreased from 9.10 to 8.63 h/day by 24 months (P = .033). No patients achieving 4-hour usage at 6 months subsequently dropped below this threshold. Neither age at implantation nor duration of deafness correlated with usage changes. Most patients lost to follow-up demonstrated at least moderate use at their last visit.
conclusionChildren with UHL demonstrate high sustained CI usage through 24 months. Although usage declined over time, this averaged only about 30 minutes per day. Early usage patterns appear predictive of long-term device adoption.
