Factors Affecting Audiometric and Speech Perception Outcomes in Hybrid Cochlear Implant Recipients.
Article in The Laryngoscope, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 3 registered trials, which are not on this map. Cited by 1 paper.
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.

Abstract
objectivesTo evaluate the long-term audiometric and speech perception outcomes in Hybrid cochlear implant recipients meeting hybrid or electric-acoustic stimulation (EAS) indications, and to identify factors, including age, sex, and duration of hearing loss, that may contribute to outcome variability. Additionally, the study evaluates the impact of EAS on speech perception.
methodsData from two clinical trials and retrospective data from the University of Iowa were combined for a total dataset of 150 Cochlear Nucleus Hybrid L24 (Cochlear Ltd., Sydney, Australia) cochlear implant recipients. Audiometric outcomes, as quantified by low-frequency pure-tone average (LFPTA; 125-500 Hz), and speech perception outcomes, including unilateral and bilateral CNC words in quiet and AzBio +5 dB SNR sentences in noise, were assessed preoperatively and postoperatively up to 5 years postactivation.
resultsFunctional low-frequency acoustic hearing (LFPTA < 80 dB HL) was preserved in 72.9% of Hybrid L24 recipients up to 5 years postactivation, with audiometric changes stabilizing around 1 year. Significant improvements were observed in speech perception both in quiet and in noise. Age at implantation was a significant predictor of both audiometric and speech outcomes, with younger recipients demonstrating greater speech-in-noise improvements and a greater likelihood of maintaining functionally aidable hearing. EAS users demonstrated superior speech outcomes compared to electric-only users.
conclusionCochlear implantation for EAS candidates provides long-term preservation of acoustic hearing and improved speech perception outcomes, particularly in younger recipients. These findings support the use of hybrid/EAS cochlear implantation in candidates with low-frequency hearing and highlight the benefit of EAS in enhancing speech understanding. LEVEL OF EVIDENCE: 3 Trial Registration: Relevant studies were registered on ClinicalTrials.gov under trial registration numbers NCT00678899 (pivotal study group), NCT02379273 (continuation of pivotal study group), and NCT02379819 (post-approval study group).
