Social Determinants of Health and Impact on Cochlear Implant Performance.
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.

interventionCochlear implantation.
main outcome measuresThe national Area Deprivation Index (ADI) is a ranking of neighborhood socioeconomic disadvantage with higher ADI suggesting greater disadvantage. The primary outcome was the change in ipsilateral CNC scores (delta CNC) at 3 months compared with pre-implant. Multivariable linear regression was used to explore the association of SDH factors on delta CNC scores at 3 months while controlling for confounders.
resultsThe mean (SD) ADI of patients in this study was 54.6 (23.9). CNC scores at 3 months increased by a mean (SD) of 31.5% (25.7%). In multivariable regression models, there was a significant interaction effect between national ADI and insurance type on delta CNC. After controlling for age and preoperative pure-tone average (PTA), for patients with Medicare insurance, every additional point increase in ADI is associated with 0.08% decrease in delta CNC. For patients with commercial insurance, every additional point increase in ADI is associated with 0.12% increase in delta CNC.
conclusionsNational ADI is a well-established measure for SDH and should be explored to better understand equitable CI health care. In patients with Medicare, there was a significant association between higher ADI and smaller delta in CNC speech perception scores. This association of SDH and CI outcomes raises critical questions that need to be explored through larger, more diverse studies to better advance equitable hearing health care.
