Trends in Adult Cochlear Implant Access and Uptake Across Ten Years of Reported Data.
Article in Audiology research, 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
backgroundAdults with severe to profound hearing loss have limited access to cochlear implants (CIs). The objective of this study was to assess the evidence to establish whether the uptake rate of CIs has changed over the past decade.
methodsA PubMed search, supplemented with manual searching, identified 15 relevant papers published from 2000 to 4 February 2025 reporting the uptake rate of CIs in adults. In addition, new calculations of uptake rates were made for 2019, based on total numbers of CIs implanted and the prevalence of hearing loss from the 2019 Global Burden of Disease Study.
resultsThere was a lack of published data on the uptake rates for cochlear implants, with very little consensus in the methods used across studies. The overall uptake rates for adults and children combined, calculated for 2019 using the Lancet Global Burden of Disease Study, showed that uptake is still ≤20% for those with profound to complete hearing loss in most high-income countries. When the global population is considered (including high- to low-income countries), it is merely 2.5%.
conclusionsDespite the cochlear implant awareness activities of recent years, the percentage of profoundly deaf individuals with cochlear implants, even in high-income countries, remains low. Uptake rates are much worse than those for hearing aid use for severe to profound deafness. Better and more accurate data must be gathered on the number of CI recipients to meet the reporting requirements of the World Health Organisation's report on hearing.
